I like checking the Yahoo Movies viewer ratings. The critic ratings for this movie average a "B" and the user ratings (only 1050 so far) averaged an "A-", which makes it worth a viewing for me. So called critics have to maintain their so called credibility by not liking popular movies too much, so they are usually lower than the citizens.

I'd give it between an A- and a B+ since the ape CGI was a little weak.

RottenTomatoes.com has an 82% critics and 90% audience "like" rating.
