Question: 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 positive review?

Answer: no

Question: Review: In this little film we have some great characters but a very shallow plot. It is actually nice to watch because Singleton does a great job at presenting the esoteric conflicts and the interpersonal relationships. This makes the viewer forget the nonexistent realism that this movie supposedly is for. In fact what we have here is all the possible cliches and stereotypes put on celluloid in a rate higher than that of a soap. Definitely not a deep movie (even if it wants to be), but better than an average college movie. Question: is it a positive review?

Answer: yes

Question: Review: I haven't seen this, & don't plan to see this movie or any other that includes Lindsay......unless & until "poor little rich girl" straightens out her life for a 2 year period beginning with her most recent arrest in July 2007.In fact, I don't know anyone that has gone to see ANY of Lindsay's recent movies. I rather imagine 2007 will be the high water mark in her movie making career, until she cleans up her act. All of the recent publicity has only hindered her movie making career, if she has any further aspirations to make any more movies Up to this time, movie producers have actively sought Lindsay for roles in their upcoming production. Now, Lindsay will probably have to go to auditions & actually compete for ANY role. Her reputation is currently "poison" & quite possible could have a negative effect on box office ticket sales on any movie she is in.Sooooo....now Lindsay is going to have to deal with "not being wanted".....is she going to be able to handle this?I wonder if even Jay Leno will want to have Lindsay back on his TV Show?All of the foregoing is merely my OPINION. I have no inside information. Question: is it a negative review?

Answer:
yes
