This is one of the most terrible movies I've ever seen. I don't even know where to begin, well, first, the cast was awful, a total of 10 actors, whom characters somehow represent the highest authorities in LA(governor, weatherman and weather scientists and of course the bad methane-gas-extractor-boss-guy) and i say "authorities" because no one else in LA seemed to give a damn about the whole thing at the moment.(you do, somehow, see a police car, though i don't remember seeing any officers on duty). Anyways, I still have to recover and find something that made sense in this movie, because there ain't much. The best worse things were the video effects. The explosions are great, as far as their sound is concerned, yeah, you get to hear awesome explosions, but the visuals on the other hand, terrible.
Yet the best part in this film was the fact that they were controlling the ultra-magnific-worldsaving-thermorocket with a Playstation controller. And no, it ain't a joke, it is a Playstation controller, though it has one extra self-destruct-button in the middle.
Well, overall it gets a 3,47/10 from me. Regarding the review, i'm sure there are many many more bugs to be found in this movie, thats the only reason one should take his time watching it. You will definitely get a laugh.
