there's brainless but 10,000 BC and The Day After are just braindead man it's impossible to enjoy any of those movie on any possible level
hey come on, at least it portrays a decent message at the end of day after tommorow about how the northern hemisphere shits all over the southern hemisphere with polution, but a twist of fate means that the northern hemisphere needs them to survive.
It's pretty melodramtic, but has its heart in the right place.
Also, the CGI is pretty incredible in that movie, although I do agree that the cold wouldn't chase them like it does in that one part. That's probably the worst part of the movie. Other than that, you can still enjoy it on a 'popcorn' level, unless you are one of these characters that will only like something that has a psuedo-intellectual message behind it.
