Review: After having seen the Canadian/Icelandic/British 2004 production of "Beowulf & Grendel," which I thought brilliant and stunning, I approached this--the first of 3 newer Beowulf movies due out this year--with trepidation. As soon as I heard "Viking" and saw the horned helmets, I groaned. These were Migration Era Swedes and Danes, not Vikings (they came later). And even the Vikings never wore horns on their helmets (horns make it easy for your enemy to knock your helmet off and then brain you). Then there's Hrolfgar's palace, which looks like a set for a movie about Greece or Rome, not 6th-century Denmark. The swords and armor look like props left over from earlier films set in various historic periods. I spotted weapons that might have been used by Crusaders in "Kingdom of Heaven," and one character was even wielding a Windlass Steelcrafts reproduction movie sword from "Beowulf & Grendel"! Beyond the basic plot of the original epic poem, the writing was dismal and the acting totally wooden and unconvincing. The biggest yuk was a secret-weapon crossbow, complete with sighting scope and exploding projectiles, that looked like something bought from Iraqi insurgents. The special-effects monster and his mom were so on steroids that Beowulf could never have torn off an arm, as he did in the poem. Thank the gods for bazooka crossbows! I could go on, but I won't.

yes

Review: My kids recently started watching the reruns of this show - both the early episodes on the N, and the later ones on ABC Family - and they love it. (I wasn't aware the show had even lasted past the first or second season) I'm curious as to what prompted all of the cast changes - I've seen them described as "highly publicized," and yet a half hours searching efforts on the web have revealed nothing but endless comments on how the early episodes were so much better than the later episodes. (Personally, I don't see a whole lot of difference - the scripts and themes remain largely the same throughout - but they do lose some great people along the way) My daughter has put the DVDs on her wish list, so perhaps the land of special features and commentary will shed some light on all of this. I also wish they'd done some self-referential humor about the changes - like on "Boy Meets World" where they drop the little sister for an entire season or so, and when a different actor later shows up playing her, they ask her where she's been and she says "upstairs," or when early series token geek "Minkus" shows up for the high school graduation, they ask him where he's been and he says "over there," pointing to the part of the classroom never shown by the camera, before saying "Hey, Mr. Turner, wait up!" and running off screen (Mr. turner being another character who left) Oh well - maybe there will be an E true Hollywood story on this or something? I was just glad to see Aunt Hilda show up for the finale - she was always one of my favorites - it's too bad it couldn't have been a more encompassing cast reunion. (The Zelda candle just didn't cut it for me) Question: is it a negative review?
no

Review: Very bad film. Very, very, very bad film. It's a rarity, but it defenitly is not worth hunting down. This Italian Jaws rip-off makes little sense most of the time, and no sense the rest. The "alligator" is not at all convincing, and many of the sub-plots go nowhere. If it's at the local video store, you may want to watch it if you're a fan of monster movies, but it's not worth hunting down. Question: is it a positive review?

no
