OK, so Soldier isn't deep and meaningful like Blade Runner or as big budget as Terminator 2 but on the whole I found it quite enjoyable.
The fact that Kurt Russell stayed in character not speaking and being virtually emotionless made the moments when his humanity broke through all the more poignant. I found his portrayal of restricted emotional development more touching than Arnie's in the T films (and before I get comments yes I know that Arnie was a cyborg and Kurt was human but the premise put forward by both films was the same).
So to the film itself, a reasonable US/Brit cast are able to flesh out this little story. Not really sure if Gary Busey and his two deputies were baddies or goodies, so was unable to decide whether I liked them or not. The colony was a little more realistic neither a misguided bunch of peace loving/gullible/cowardly hicks who get wiped out from the get go nor a group of subversive aggressive terrorists paranoid about offworlders and each other.
Kurt Russell is good and unlike other comments I do not feel this will have a negative impact on his career (unlike maybe Escape from LA - sequels are such fickle creatures!). Sean Pertwee has really done his late father proud by continuing the families noble Sci-Fi lineage. And the rest of the cast helped flesh out this pathetic band of people making the most of a bad situation and not doing too badly.
If you see this on your TV schedule I would recommend giving it a chance. I don't think you will be disappointed.

Some have praised _Atlantis:_The_Lost_Empire_ as a Disney adventure for adults. I don't think so--at least not for thinking adults.
This script suggests a beginning as a live-action movie, that struck someone as the type of crap you cannot sell to adults anymore. The "crack staff" of many older adventure movies has been done well before, (think _The Dirty Dozen_) but _Atlantis_ represents one of the worse films in that motif. The characters are weak. Even the background that each member trots out seems stock and awkward at best. An MD/Medicine Man, a tomboy mechanic whose father always wanted sons, if we have not at least seen these before, we have seen mix-and-match quirks before. The story about how one companion, Vinny played by Don Novello (Fr. Guido Sarducci), went from flower stores to demolitions totally unconvincing.
Only the main character, Milo Thatch, a young Atlantis-obsessed academic voiced by Michael J. Fox, has any depth to him. Milo's search for Atlantis continues that of his grandfather who raised him. The opening scene shows a much younger Milo giddily perched on a knee, as his grandfather places his pith helmet on his head.
And while the characters were thin at best, the best part about _Atlantis_ was the voice talent. Perhaps Milo's depth is no thicker than Fox's charm. Commander Rourke loses nothing being voiced by James Garner. Although Rourke is a pretty stock military type, Garner shows his ability to breath life into characters simply by his delivery. Garner's vocal performance is the high point. I'm sorry to say Leonard Nimoy's Dying King is nothing more than obligatory. Additionally, Don Novello as the demolition expert, Vinny Santorini, was also notable for one or two well-done, funny lines--but I've always liked Father Guido Sarducci, anyway.
Also well done was the Computer Animation. The BACKGROUND animation, that is. The character animation has not been this bad for Disney since the minimalism that drove Don Bluth out the door. The character animation does nothing if not make already flat characters appear even flatter. Aside from landscapes, buildings and vehicles there isn't much to impress.
The plot was the worst. Some say hackneyed or trite. I'm not so sure about that. Any serviceable plot can be made into something new with the proper treatment. Shakespeare often started from a known story and plot and was famous only for putting on a new coat of paint. So the treatment is the thing. And _Atlantis_ obviously lacks that.
I cannot begin to go into all the logic gaps without a spoiler section. The plot was bad. The plot's bridges snap like twine and the ending does not make sense. To add to that, the script and the animation is peppered with annoying sloppiness.
** SPOILERS **
1. Right at the beginning when Milo reveals that runic or Celtic symbols have been wrongly transliterated and the "Coast of Ireland" should read the "Coast of Iceland", we begin to have problems. The writers of the script would need to know the British take for Eire or Eireann as "Ireland", and completely ignore the older, Latin term Hibernia. But more than this, they need to know of the Vikings conspiracy to call the greener island Iceland and the icier island Greenland.
By making it the matter of a mis-tranliterated "letter", the writers have doomed themselves to requiring a runic version of English and a post-Roman date on the script. Since this is long after Atlantis was supposed to have sunk into its undersea cave. And without visible clues and less technology than Milo had, made the inscription far less trustworthy.
2. The Shepard's Journal could not be written before the sinking of Atlantis, or it would know nothing about the cave or the crystal lying "in the King's eye". It must have been written after the sinking, but without even the technology that Milo's expedition had, how the heck did anybody get by the Leviathan. So how could it know more about anything after that? And why would it be written in Atlantian?
Automatic writing and clairvoyance or astral travel can explain these things. However clairvoyance and astral travel do not require the shepard to write in Atlantian. So it's got to be some sort automatic writing. Since noone left in Atlantis can read, it must be the spirits of the crystal beaming messages to the surface. This would have made more sense. But could also have been explained within the movie: Milo could have discovered that this power had been calling him all his life--appeared in dreams, etc. This needed to be explored in the movie.
3. The Atlantians should simply not be able to comprehend modern languages. No-one expects that the original Indo-Europeans would be able to converse in Europe, anymore than Romans would understand that hard "c"s or their day became French "ch"s (pronounced like "sh"s, no less!)
4. Current Atlantians were alive before the cataclysm--when apparently they *could* read, yet now are unable to read what they used to, or operate similar machinery.
5. The Mass Illiteracy points out a crucial flaw in the movie. NOTHING seems to have happened to this culture. It seems suspended in air until Milo can rescue it. Even though it appears that life is not a constant struggle for survival, no-one wants to compose poetry or write novels and perhaps it is a combination of Atlantian school systems going downhill toward the end and lack of good fiction that caused Atlantis to fall into illiteracy.
5. Kida can be excused for not knowing how to read or operate the machinery if she was so young when the Cataclysm of Stupidity set in--But ANY OF IT **HARDLY** qualifies her father for Deification!! Kashakim's foolishness almost single-handedly wiped his people from existence. Killed a bunch in the cataclysm, stalled progress (not a lot killed here, but he oversaw a massive slide in culture and progress) until someone could take the crystal to kill everybody, if they weren't boiled in lava first because the Giant Robots weren't there to protect them.
A bolt of blue electricity should have shattered Kashakim's likeness, when Kida tried joining her father's image to the circle of GREAT Kings of Atlantis!
6. Even though Milo was the only one who could read Atlantian, Rourke and others knew enough to look through a book of gibberish and find a page on a crystal--which he knew to be a crystal and not some stylized astrological or "phases of the sun" diagram.
7. If Milo's grandfather had told Rourke about it, it still does not explain what how Rourke would have suffered from Milo's reading it as part of the book. Ripping out the page--which was dog-eared in Rourke's hand, even though Milo found NO sign of a torn page in the book apparently--only was there to tip off the viewer that "something was not quite right". Unless the word "crystal" would have set alarms off in Milo's head that somebody would try to steal it, Milo would have suspected nothing. It's just thick-headed foreshadowing.
8. The crew's "double-cross" was not a character change. We learned that Vinny, Sweet, Audrey and Cookie had been going along with Rourke from the beginning. However, the "change of heart" falls flat. It was a change, and needed to be better motivated. Hard to do with characters who weren't given anything to begin with.
9. Niggling little bit that the lava flows up over the dome, instead of filling in the rest of the area that we view the sequence from. It's liquid; it will not flow over the protective dome until it fills up all lower areas.
10. The ending STINKS!-- and makes no sense other than to appease political correctness. With it's powersource restored, Atlantis is no longer a weak power, needing coddling. The giant robot guardians and the sky-cycles shooting blue lightning suggest that they have less to fear from us than they might. The technology is superior to ours, and definitely to early 20th-century. In the end Milo needs to teach the Atlantians to read, for what? The whole idea is to leave their little quiet, chastened culture alone, not to send it into hyperdrive.
** END SPOILERS **
Perhaps, the Lost World plot and the turn-of-the-century setting should give me a hint that this is more an homage to pulps. The failures I find with the film agree with this idea. But I am at a loss why I should pay to see thin characters and plot holes simply because many dime novels had them as well. And pulp stories is part of the "crap they can't sell adults anymore", anyway. We have become a bit more sophisticated and our pulp needs to grow up as well. Raiders of the Lost Ark lost none of its pulp feel and avoided so much badness.
4 out of 10--the movie is enjoyable but as I think about the plot, it seeps ever lower.
