I saw a screening of this film last Saturday and I must say: I was quite disappointed. The animation was gorgeous but I think they could've done a much better job with the actual film itself. The comedy was too cutsie, which I did kind of expect. The directing and staging of the whole thing was kind of off. I liked the setting and the premise though. I just don't like how Kirk DeMicco (director of Space Chimps) executed it. I did, for once, kind of enjoy Nicholas Cages performance. Although it wasn't the best of the film, I personally would have nominated Cloris Leachman for the best voice and best performance of this movie. I also enjoyed Emma Stone's character. So basically, the story goes as follows: "Surviving in a volcanic world is tough enough, but caveman Grug gets a rude awakening when an earthquake forces him to leave behind the only world he knows. With his family in tow, he ventures out into the volatile world in search of a new home. The situation becomes even more complicated when Grug's family — in particular his oldest daughter, Eep — falls for a nomad named Guy they encounter on their dangerous journey. This quirky, imaginative stranger's search for 'tomorrow' is at odds with Grug's reliance on the traditions of yesterday." This description was taken from Wikipedia.
