The first two reviews pretty well summed up this great movie! Funny, fast paced and lots of in jokes, past film references, sight gags from other Aardman films, a good story and was well executed!
I highly recommend this movie if you love "Chicken Run", and "Wallace & Gromit". If you have not seen any of Aardmans other shows/movies you will miss a few sight gags, but that is certionly no reason not to see this! So in the end; This movie is a must see and definitely fun for the whole family.
