This is by far the best Ice Age film and on of the best animated films I have seen. I laughed out loud at times and the kids laughed out loud at others. It has something for everyone. Really well done.
As the title says, not bad but not great either. There were moments of brilliance but a lot of flat dull time. The 3-D was somewhat gimmicky, compared to Disney 3D and I definitely would never pay for the IMAX 3D again. Compared with the Tru3D this was no where near as good. The glasses hurt and were not adjustable so my 5 yr old had trouble with them falling off her face. I had just enough fun to recommend it to friends but it would be with the caveat of NOT going to the IMAX screen.
