It's pretty good, you'll like it if you liked the first one.

Rating: 7/10 (5 December 2009)

More of the same--Manny, Sid, Diego, this time w/ a twist of Queen Latifah as another Mammoth and a couple of whacky possum brothers. It's a good sequel. This time out, the big glaciar walls are breaking, they're headed south to some natural-formed ark, Skrat's along for the ride, hilarity ensues.
I enjoyed the mammoth as possum gags, the under-water fights w/ the shark things, the CGI animation is clearly improved, the voice-work is just as dead-on now as it was in the first.
Clearly you'll like this if you liked the first. Sid is the best part of this, him and Skrat.
