What's your number?
Okay so the plot's obvious, but the acting actually isn't terrible, there are some really good parts. So despite it being quite derogatory to women, if you look at if from that angle, it's worth a watch. Plus, it does kinda ring true. 7.5/10
EDIT:Watched The Change-up yesterday as well. Have not laughed so much at a movie for quite some time-some parts are hilarious! Proper immature comedy though, but despite being a quite overdone storyline, this was a bit more fun than the normal kid/adult bodyswap. 8/10
