Ice Age: Continental Drift may have had a personnel boost from the likes of Denis Leary and Queen Latifah but as far as the critics are concerned, the latest instalment in the Ice Age animated movie franchise is floating adrift in a sea of uncertainty. Lukewarm reviews have fallen either side of the fence and the 3D film is currently hovering at an unsatisfactory 55 per cent on the Rotten Tomatoes review aggregating site.

Anton Bitel of Film 4 was one of the first to stick the knife in, describing the movie by saying "this latest installment feels like a rudderless ship of ice floating in tropical waters" and Roger Ebert, of the Chicago Sun-Times didn't have many positive words to say about the film, either: "The characters are manic and idiotic, the dialogue is rat-a-tat chatter, the action is entirely at the service of the 3-D, and the movie depends on bright colors, lots of noise and a few songs in between the whiplash moments."

It's not all bad news, for the cartoon caper though, The Hollywood Reporter's Megan Lehmann said "It's familiar, drawn-out shtick, and the humor lacks the subtlety of the first and best Ice Age, but there are some visually inventive high points." It's hardly high praise, but at least there is some salvation for Ice Age: Continental Drift, which currently looks as though it's in danger of sinking into the depths of cinematic history, without a trace.
