I thought the characters were cute. Seth Rogen and Paul Rudd were the best voices I think. A bit misleading on the previews/trailers as the movie seems appropriate for little kiddos (2-3 yr olds) but my toddler was scared by the Insectosaur and the Robot and it was quite loud with lots of peril. My older children enjoyed it and there is quite a bit of adult humor thrown in for good measure (I love the "convenient truth" comment by the Missing Link).
