Review: This movie has some things that are pretty amazing. First, it is supposed to be based on a true story. That, in itself, is amazing that multiple tornadoes would hit the same town at night in the fall-in Nebraska. I wonder if the real town's name was close to "Blainsworth" (which is the town's name in the movie). There is an Ainsworth, Nebraska, but there is also a town that starts with Blains-something.It does show the slowest moving tornadoes on record in the the seen where the boys are in the house. On the other hand, the scene where the TV goes fuzzy is based in fact. Before Doppler radar and weather radio, we were taught that if you turned your TV to a particular channel (not on cable) and tuned the brightness just right, you could tell if there was a tornado coming. The problem was that by then you would be able to hear it. Since I know something about midwest tornadoes, it made this movie fun for me. I enjoy it more than Twister. I mean, give me a break-there is no way you could make it through and F5 by chaining yourself to a pipe in a well house. Question: is it a positive review?

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.

Review: It is a pity that you cannot vote zero stars on IMDb, because I would not have hesitated! In fact I would go so far as to say that this film was in the negative stars. I, like many others, bought this film thinking that because it has Michael Madsen in it, it could be good... No chance! This film was shocking! Imagine a movie length 'The Bold and the Beautiful', well, Primal Instinct did not even come close to that good, and I had previously thought that there would be nothing worse than a movie length 'The Bold and the Beautiful'. Michael Madsen, how could you do this to us? The worst part is, I didn't fast forward a bit, I was hoping that at the end they would reveal that it was all some sort of sick joke, that they thought it would be funny to make us watch such a horribly bad film.Where do I start...? Directing - Zero Stars, Screenplay - Zero Stars, Acting - Zero Stars, Cinematography - Zero Stars, Digital Effects - Zero Stars, Production Design - Zero Stars, Make-up - Zero Stars, Casting - Zero Stars, Editing - Zero Stars, Trailer - Half a Star, Graphic Design - Half a Star, DVD Menu - Half a Star.However I think that it is very important to have seen bad films just so that you know what a really bad film is, so for that reason I am happy that I saw this film, just so that I have a bad film to put at the bottom of my list.
