Detroit Free Press:
Although we eventually warm up to the amiable Ice Age, we still feel as if we're watching Shrek on Ice, or Mastodons, Inc., so formulaic is the storytelling.
If all of Ice Age had been about the tenacious rodent's misadventures, the movie might have been a minor classic. But Scrat is a minor supporting character, and Ice Age is just passable entertainment.
Ebert & Roeper:
Ice Age won't drop your jaw, but it will warm your heart, and I'm giving it a strong thumbs up.
Real Ice Ages were no jokes. They lasted about 100,000 years and froze most life on the planet. But as long as Leguizamo's Sid and Wedge's Scrat are on screen, this one warms you with laughter.
New York Times:
Mr. Wedge and Mr. Saldanha handle the mix of verbal jokes and slapstick well. Their film falters, however, in its adherence to the Disney philosophy of required poignancy, a salute that I'd hoped the movie would avoid.
Vivid conception with amusing, witty stretches that offset the intervals of goo.
It has taken 20th Century Fox a while to land on the animation scoreboard. Now it has. Ice Age is the coolest animation in town.
Los Angeles Times:
As written by Michael Berg and Michael J. Wilson from a story by Wilson, this relentless, all-wise-guys-all-the-time approach tries way too hard and gets tiring in no time at all.
The movie suffers every time the creatures have to say the words the screenwriters have foisted on them.
Paul Clinton (CNN.com),
This is one of 20th Century Fox's first ventures into the world of animation, in partnership with Blue Sky Productions, and they've hit a home run.
[D]espite its familiar subject matter, Ice Age is consistently amusing and engrossing ...
Ice Age never matches the brilliance of Toy Story or the heartfelt heft of Shrek, but it's an antic and sweet-spirited pleasure.
Globe and Mail:
No evolutionary leap forward in the world of computer-generated animation, just another palatable, familiar children's diversion in shiny new form.
Dallas Morning News:
Produced by 20th Century Fox, Ice Age falls short of classic status. But it's one of the best such features not to wear the Disney or DreamWorks banner.
From the squirrel's mad, droopy eyes, to the rumba rhythms of Manny's rear end, to the way Diego settles into sleep like a tabby, these creatures are alive enough to love, and lament.
Kids, of course, will love Ice Age. Adults will be entertained, but no more.
There's enough classically derived Road Runner-type fun to keep most family audiences happy. But the characters betray their contrivance.
It's clever enough to amuse adults, yet sufficiently kid-friendly to delight tykes with diminutive attention spans.
Full of visual dazzle, engaging characters and a reasonably sprightly narrative.
