I have mixed opinions on this one, it wasnt as clever as the first, and not as daft as the second. IMO that is. It has big plot holes, which I hate. It was a little boring near the end, because you can tell all of the Writers ideas had gone. I was wrong however on the Roller Coaster set piece, that was the best part of the film, definately.
It was worth my Ticket I guess, but I wouldnt recommend seeing the film ( unless you have seen all of the Good Good movies out now )
