Question: 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.

Question: Review: This has to be one of the 5 worst movies ever made. The plot looked intriguing like that of Passenger 57. But with the latter movie it somehow worked a lot better. The plot has been worked out in the worst possible way. Just a few of the awful moments in the movie, A flight attendant is standing in the opened doorway of a flying 747 and trying to close the door without being sucked out by the 250 mile per hour winds?!? Thereafter the lands the aircraft from a few miles out starting at 8000 feet, thats impossible even for 747 pilots with thousands of hour experience. When on the runway (perfectly straight of course) she is instructed to pull on the flaps, HUH!! Come on flaps are there to ensure lift at low speeds, when on the runway you use thrust reverse on the engines and give maximum power! I can go on and on about little and mostly big mistakes in the movie, but then my reply would become the size of the English dictionary. This is a movie you want to miss, take my word for it! Question: is it a negative review?

Answer: yes


Question: Review: Another entertaining Travolta dance flick! GREAT MUSIC, mood, and scenes. Debra Winger is beautiful! Like "Saturday Night Fever", this macho film features extremely improbable scenes of beautiful women falling for Travolta and almost begging him to have sex with them. Question: is it a negative review?

Answer:
no
