[EX Q]: 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.

[EX Q]: Review: This movie is rated a classic on sentiment not on any quality of movie-making. It moves from the unlikely to the unbelievable, from the unrealistic to the ludicrous.The unbelievable plot revolves around an attempt by two British soldiers and a Hindu gofer to rescue a third soldier who has been captured by insurgent Indians. In the later scene we see a full regiment with drum and bagpipes marching into an ambush. In the British army, a sergeant does not order up a rescue attempt, and if you get past that, he does not attempt it with only one other soldier and an Indian servant when there is a full regiment on hand. The Indian insurgents are so incredibly inept it is laughable...there are hundreds of them but they can't hold their prisoner or kill the two rescuers, of course not. At one point we see the British soldiers throwing blocks of stone down from the battlements at the insurgents, who are scattered around the mountainside in ambush...one would have to have an eggplant for a brain to think this would do any damage. After Cary Grant as the rescued prisoner is shot, he lies on the floor looking around at the water boy...hardly the actions of someone who has been shot in the back. The water boy bravely blows a bugle (which comes from nowhere) to sound the alarm...this he does by standing up high on a wall so he can be seen and shot by the bad guys, and we shed a tear as he keeps trying to sound more notes as he is repeatedly shot and the bugle call breaks up into feeble squawks...instead of blowing the bugle while hiding behind cover as anybody with half a brain would do. This scene has deservedly been parodied in comedy sketches. If they wanted to make a Buster Keaton comedy, they should have hired Keaton and done it better. Question: is it a negative review?

[EX Q]: Review: I just saw this film last night in the 2006 Tribeca Film Festival and it seriously makes me wonder if the folks at the festival actually screen the films before selecting them. The film was simply awful - I say that without hyperbole or ulterior motives - it was awful. Matthew Modine's days as a leading man are way over. Gina Gershon sported an inexplicable and unnecessary English accent - she should be ashamed of her participation in this film. Gloria Reuben had a weird little cameo in it - she should also be ashamed. The script was terrible and the we were given absolutely no reason to care about the characters. I highly doubt this will be picked up, but then again, people in Hollywood are known to make mistakes sometimes. I really think "Kettle of Fish" is a serious contender for the worst movie I've ever seen. Question: is it a positive review?
[EX A]:
no
