I liked it! (How can you NOT love Mel's gorgeous voice?!)
Good for the kids - lots of humor that they can get into (there is one scene in the beginning that could be a tad upsetting to some of the younger set.)
Lots of humor, though, for the adults, too. References to Star Trek, a Steve McQueen film and others that go over the kids' heads, but the adults find humorous.
If you loved Wallace and Grommit, you're going to love this one - the creators carried the W and G techniques over very well. The expressions in the faces of the chickens were superb. Some of them very subtle - watch closely!
Just don't plan on eating chicken afterwards for a while - you get too close to the characters!
