i saw it last night. initially, i almost walked out of the cinema, as nothing grabbed me. but when all hell breaks loose it gets very interesting. my favorite 2 parts of the film are..
spoiler.
when the four of the guys/girls are running down the street then a rocket go's whizzing past their head toward the creature, you dont actually see iT because loads of troops and tanks go past, firing all their weapons and the characters cant get their heads up because of all the firing, at this point did i realise the sound was immense, it felt as though i was in a battefield!
also, when they are in the helicopter trying to escape, and the B-2 bomber flies over head and carpet bombs the creature, and the guy is shouting and cheering because they hit it (i was aswell, obviously not shouting it out in the cinema though) and from nowhere it jumps through the cloud and nails the heli, and the guy is praying to god that they don't die when it is falling through the sky (ive never panicked in a film before like i have watching that part lol)
overall i give it 9/10
