While I wouldn't say this is a bad movie, there's a lot of flaws in this one. The movie contains a lot of cliches that you see in any disaster movies like the main character discovered something, her boss refused to listen, her teenager daughter going out with her friends, and people not listening until it happen. It's easily predictable with each of these and some of it feels rush like the boss and townsfolks refused to listen. Also, there a couple of plot point that feels important, but end up not using it like that one small romance with the daughter character and one of her friends. The movie have the tornado shooting ice out of itself which is ridiculous and shows how dangerous it is. And the CGI of the tornado doesn't look bad at all. But there are some questionable moments like how the tornado is so close that none of the cars ever gets stuck into it. And I already guess on how the movie is going to ended.
Super Icyclone has some enjoyable to be found, but it full with a bunch of cliches that you see in other disaster movies out there.
