No I'm pretty sure its the 3rd. Plus technically surely its a prequel because the dinosaurs died out before man arrived so the baby that existed in the first one wouldn't have existed during the period of the third film. I realise that this makes me sound like an uptight a$$hole but also why the hell would the mammoth have helped out the baby in the first one. Man didn't just wipe out his family like the flashbacks reveal, we were also responsible for pretty much wiping out his entire race. Thats like having a film about Anne Frank where Anne Frank's father goes on a quest in order to re-unite Hitler with his lost son! Talk about historical innacuracy.

I don't know why they even bothered to franchise Ice Age, I really don't like the series. It had a minimal amount of charm and the most basic computer animation. You can pretty much tell that a film is going to be crap when the most recognised character from the series and the one they use to market the film doesn't have any influence on the main plot whatsoever.

The annoying thing is I'm going to have to go to the cinema to see it because my brother wants to go and if I don't take him he wont get to go.
