Review: This is only a response to the yahoo who says this movie is more realistic than the classic, genre defining MASTERPIECE, Jaws. Yes, brainiac, great whites(and other species of shark, bull, black-tip, oceanic white-tip, tiger)have been known to populate areas where easy prey is found. Humans don't often make it onto that menu, granted, but the shark in the film was repeatedly pointed out to be exhibiting abnormal behavior. It's not like it's never happened. The odds of a killer whale destroying nearly a whole town, singling out a human nemesis, sinking several dozen thick hulled North Atlantic fishing boats and knowing when certain people, all friends of the aforementioned "nemesis", are close enough to the water for it to reach, are so slim as to be laughable. Much like this turd of a Jaws knock-off. Laughable. Great white sharks are also known to frequently chew on boats, protective underwater cages and people on rafts and surfboards, as they look like seals from below. A shark the size of Bruce(if you don't know, look it up)would be more than capable of sinking a boat like The Orca(hey! that's the name of the blatant rip-off we're discussing!), as it would weigh upwards of 6,000 lbs. I could go on, but I don't need to. Jaws is amazing(better acting, better effects, better music, better writing), Orca is crap(BLATANT rip-off of Jaws, lousy writing, abominable effects, most ridiculous plot this side of an Olson Twins flick). It doesn't take a masters from Columbia University to see that. Watch better movies. Question: is it a negative review?
yes

Review: From the blocky digitised footage to the acting that makes Keanu "I'm so wooden I could be a Plank me" Reeves look like an Oscar winner this film bites (pun not intended). The best thing about it is the box of eRATicate in the 2nd segment (which out of the three seemed to be the strongest piece in terms of storyline and 'twist'). Wish I'd spent the £3.99 it cost me on something else, like erm.... Natural Born Killers: Directors Cut. If you do buy this, you're really in for a disappointment, do yourself a favour and avoid it like the plague. If you're looking for something amateurish and with actors that are more wooden than a 2x4 then go ahead. However if you want some quality werewolf action look elsewhere, like Dog Soldiers, Wolfen, Romasanta:The werewolf Hunt. Question: is it a negative review?
yes

Review: Spooks is enjoyable trash, featuring some well directed sequences, ridiculous plots and dialogue, and some third rate acting.Many have described this is a UK version of "24", and one can see the similarities. The American version shares the weak silly plots, but the execution is so much slicker, sexier and I suspect, expensive.Some people describe weak comedy as "gentle comedy". This is gentle spy story hour, the exact opposite of anything created by John Le Carre.Give me Smiley any day. Question: is it a negative review?

yes
