"2012" is exactly what you expect: a special effects extravaganza with world wide destruction at every corner. It gave me everything I wanted.
"2012" is not the best movie. The characters are not very good and the acting is mediocre at best. But the destruction scenes are incredible. It was very thrilling.
The director, Roland Emmerich, has directed two previous disaster films: "Independence Day" and "The Day After Tomorrow". In "The Day After Tomorrow", Emmerich had the film more character based and only had a couple quick disaster scenes. That film did not work at all. For "2012", Emmerich learned from his mistakes and gave us one disaster after another. It was great.
The special effects in the film are top notch. Some of the best I have seen. There are so many special effects shots what with floods, earthquakes, and volcanoes to name a few.
"2012" is great fun if you go in with the mindset that you just want to see things be destroyed. Don't expect to get attached to the characters. It is not that type of film. This is just a thrilling adventure where you want to see things break, crumble, burn, drown, and die.
B I recommend it.
