If you enjoyed the series and the first movie then you might have a few qualms about this movie but overall it's a fun movie with quite a few laughs. There were some very corny parts in it but they were few and far between.
I went to this movie all excited because of all the hype about it. All the reviews were generally very good that I read. The movie just didn't do the reveiws justice IMO. It, of course, like all Pixar movies had great animation and beautiful colors but to me the story was a bit slow and lacking. I found myself laughing no more than 10 times in the whole hour and a half movie and it just seem to sometimes drag on without really going any where. There were some moments that really worked but there were just too many moments that didn't for me.
