Just got back from seeing this ... I am likely to get banned from the forum for saying this, but:
I think there might be too much bass in it!
Seriously! I am not sure I want to run my SubM on loud, windy rumbling for what amounts to half the film ... I bet this will be filtered on BD as it has the potential to destroy subs!
Other than that is was a LOT better than I was expecting and definitely not a remake of Twister.
Once it started I was hooked and it all seems to finish too soon - a good sign for a popcorn flick.
