Actually kind of like this one - the jokes are pretty good ("James Bond never had this problem" and anything those mice say) and the CG on the guinea pigs looks pretty amazing. Not to mention Disney got a pretty solid cast to voice this (Cage, Cruz, Buscemi...) and star in it (Arnett, Galifianakis, Nighy). I say they have a summer hit on their hands.
