I really wanted to like the movie, but it was difficult to invest in the characters from the beginning. Undefined goals and a fast pace of contrived clichรฉs pushing too hard for laughs left the aufience with liitle to hang on to, except good casting. When the double switch came (yes, four people this time) it as difficult to know who was who and why: I kept wishing there was a label on the screen to help. Less is often more in comedy and '13 Going on 30' is a good example.
