[EX Q]: Review: I am guessing the reason this movie did so well at the box office is of course Eddie Murphy. I think this was his first movie since "Beverly Hills Cop" so at the time he was hot. Considering that one made over two hundred million and it was R and this one made about 80 million and it was pg does say it was not all that popular. I have never been a big Eddie Murphy fan, so that is probably another reason I didn't care for it much at all. This one has Eddie as some sort of finder of lost kids. He must find the golden child or the world is in terrible peril. The plot is very bad, but as bad as it is it does not compare to the special effects. I had seen better stuff done in the 70's than some of the stuff this one offers, Ray Harryhausen did better stuff. Still the main reason you see a movie like this is because of Eddie, unfortunately he is not very funny in this one at all and it just seems stupid to put him in the "Raiders of the Lost Ark" type scenes. I guess they were hoping for a fish out of water effect, but to me it just did not work. Question: is it a negative review?
[EX A]: yes

[EX Q]: Review: This is one of the best of the genre. I saw it twice about 25yrs ago and have not had another opportunity to see it again since then. It rivals the Zatoichi series (also starring Katsu) in exciting swordplay. Question: is it a negative review?
[EX A]: no

[EX Q]: Review: This is blatantly a futuristic adaptation of Jules Verne's "Mysterious Island". The sound editing is pretty bad. You hear the dialogue on set and you hear the voices being recorded on a recording booth at the same time! This is an amateur film with actors from Boston and shot around New Hampshire. For those living in New Engalnd and who is reading this comment will be wowed with a capital W. This film is full of flaws. You get to hear the director's voice giving directions and giving out directions to the actress. "OK now stand up." As for the other characters. There is this guy who talks with his mind instead of his voice and this blue alien. The alien guy talks with a deep voice. When he is yawning or grunting when he is fighting you hear the actor's voice. As for the special effects, man! This was Brett Piper's early work for crying out loud! The creatures are good but the animation is jerky. Really jerky. Sort of like Karl Zeman animation in JOURNEY TO BEGINNING OF TIME (1955). The special effects are imaginative. Thge music is good. Bottom line, this film makes EQUINOX or PLANET OF THE DINOSAURS look like a Ray Harryhausen epic. Did you know MYSTERIOUS PLANET was a home movie and was on a shoes string budget? A must watch for aspiring film makers. Question: is it a positive review?
[EX A]:
no
