This is the type of film I would expect from their directors previous efforts (independence day and the day after tomorrow) a B movies with digital effects.
the story and characters were silly, even the digital effects could not raise this film from its low brow position.
I expect only very young children would like this one, except it's audience it limited to 12 and above!.

Prepare to shut off your brain for this one. As with alot of blockbusters, its full of lovely things to look at (the mammoths look especially stunning), but the wooden acting does nothing for the dull plot that leaves no real characters to care about.

I'll say right off that I actually enjoyed this film- as other reviewers have said there are a few plot holes but if you can go with it, the film is really quite watchable. The main problem with the plot is that it's somewhat geographically confusing- mammoth hunters (so northern hemispere) walk over mountains and then get attacked by predatory birds (so Papua New Guinea/New Zealand), then walk on again into Africa! It's not going to win any oscars, but it's still quite good popcorn fun- sort of the Scorpion King meets One Million Years BC. How much the inconsistencies bother you will affect whether or not this film is for you or not.
