Its toilet. Some of the worst cgi for the "wolves" I've ever seen, and the dad seems to walk from Washington to New York in a day. Across a snowcap.
It also irritated me the way all the world scientists were looking to the Americans to provide the answers (as though they've ever given a f*** about global warming). And of course the scene where us eccentric english are watching a game of Soccerball on the TV (manure of course), with the guy going "kick it ! KICK IT !" cos thats what we all shout when watching saaaacccurrrrr.
The most far fetched bit was near the end when the Americans all started heading south into Mexico...totally unbelievable.
I watched the end of it once and it struck me as atrociously shit.
I think that was meant to be a slyly ironic dig at the US immigration policy towards Mexicans.
Jesus, relax, it's just a film meant to entertain, as Trufflehound said :-
