We need Chris Wedge back here

Rating: 7/10 (13 April 2006)

Just saw it just commenting it.
Ice Age 2 starts in the same premise as the original. The Squirrel is that Apocalypse Angel, armored with a deadly nut. The meltdown happens both in the movie and in the theater, as the jokes are not as hilarious and original as the ones on the first movie, the "love" affair between Manfred and Ellie is funny and believable enough to satisfy adult viewers.
Technically the movie is not better than the first one, as it's low and rush design is a card on favor of this, soon, franchise. You wont find better water textures or amazing creature designs. Just the classic characters we saw and that we all know. A positive point: There is no humans, so the connexion with the old cartoons is completely lost, and this is more based on a screwball comedy.
Negative point to finish: It doesn't reach the heart as much as the original did. But is worth it to enjoy it in the theater.
