What I will say is that it's as good as you'd expect it to be. Very enjoyable in fact and as much for adults as for kids with humour aimed at both age groups (some which will go way over the kids heads without being too obvious ;-p).
Puss in Boots is particularly cute at times.....
Overall it's not as good as the first installment - but that's because we know roughly what to expect - but is a very good film in its own right and certainly stands up to the sequel test.
School Report: B+ (Go see it - and stay through at least part of the credits to see the extra scene!!!)
