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: While some performances were good-Victoria Rowell, Adrienne Barbeau, and the two Italian girlfriends come to mind-the story was lame and derivative, the emphasis on the girlfriend's racial background was handled clumsily at best, and the relatives were mostly portrayed as stereotypes, not as real people. I found myself wincing uncomfortably at many moments that were supposed to be funny. I can hardly comprehend why the local paper here in SF said this was a good movie, and wonder WHO posted the glowing review here on IMDb. Very disappointed in this movie, and mad I actually went to a theatre to see it, based on the faulty connection to Garden State, which is a far funnier, more inventive, and touching movie than this one. I must especially mention the emotional climax in the church, which was so wooden and by-the-numbers that I nearly left, and some in the audience actually DID. THAT was followed by a silly climax at the graveyard, which I saw coming 10 minutes before it happened. I really don't like being misled to spend my money so uselessly.

no

Review: Pearl S.Buck was a brilliant author that was a first American lady won Nobel prize in literature in 1938 and received her prize with Enrico Fermi an Italian Physit.She wrote this romance in 1931 which was a second one after her first novel (East wind and West wind) in 1930 and her beginning in literature was fantastic upon her premier novels.she won in 1935 (Pulitzer prize) in literature on her eternal novel (The good earth) which made a brilliant panorama on the life of Chinese peasant (Wung Lung) and his wife (O-Lane) and their efforts to face the hardness of hard positions in their earth to reach for their big fortune by their shoulders.Paul Muni succeeded in this role as Chinese peasant that he prepared himself in this role upon his sittings with Chinese people in San Francisco in their town to be Chinese exactly as a real and true.Shara Reiner succeeded in her role as (O-Lane) by this brilliant evidence that she won An Academy Awarded as a best actress in 1937.
