This film was almost unwatchable. The only reason that I stayed awake while it played was the people sat next to me who were laughing every so often and also the fact that I knew I could watch something better afterwards.

This movie is HILARIOUSLY funny. I'm not sure why it has such bad reviews. My only complaint is that the antagonists barely got ANY screen time. I'm just glad they had development! :). Granny is defiantly the best part of this movie. She has so many great one liners. Really hoping for a 6th Ice Age movie!!!!

We saw this at home on DVD from our public library. About halfway through my wife commented "This is not as good as the first one." True, nor as good as the second one, or the third one, etc.Part of the initial enjoyment was the novelty of the various wild animals getting along in prehistoric times, during the Ice Ages. Never mind that the actual chronology is inaccurate. In fact there is an 8- minute "extra" on the DVD where Astrophysicist Neil Degrasse Tyson addresses a number of the "scientific" points in this animated movie and explains why they might be grossly different from reality. All in fun of course. He even voices one of the characters.Where the other movies featured a short segment of Scrat getting into a bind, the story here in essence features Scrat's bind within the core story. Because of Scrat's ineptness he accidentally sets in motion events that created the Solar System as we know it, forming Jupiter's giant red spot, formation of the asteroid belt, the moon's orbiting around the Earth, and a few others.The big one amounted to an asteroid that would hit Earth soon and result in another mass extinction, all because of Scrat's ineptness. So all the animals on Earth have to pool their wisdom and strength to divert the asteroid.It runs 90 minutes and often gets tedious, the core story interrupted by sight gags and short vignettes. I laughed a few times but if I had never seen this movie it would not have been a significant loss.

You gotta know when to stop. This franchise has run a couple of movies too long. Now concentrating on this movie only, not the franchise, plainly put, it is a bad movie. If you are a die hard fan and want to pick positives and try desperately enough, you can do so. I am not that desperate and I take my movie watching pretty seriously and there is nothing good I can say about this movie. There is no point in going into the plot and dissecting it. Scrat used to be funny, but that seems to be a lifetime back. Sid used to be lovable, but I can't even remember the last time I felt so. There is no life in this cow, let alone milk.
