DVD: Ice Age 3, For retail & rental (20th Century Fox)

Instead of bothering with a plot, the screenwriters of IA3 have devised enough fast and furious set pieces to furnish a videogame and a theme-park ride, and then glued them together with the pun-heavy babblings of a cast consisting almost entirely of wacky sidekicks.

Still, it's nowhere near as humdrum as IA2, and parents can take comfort in the knowledge that it gets more entertaining as it goes along. By the time it reaches the cracking final sequence, any resistance will have thawed.
