I settled down for an enjoyable piece of light entertainment, but realised quickly that while it may be light, this film fails to entertain.
Contrived situations would be perfectly acceptable if funny or interesting. There were such nonsensical characters that we actually guessed what would have changed for each female character (or "victim", possibly) in the time between our "hero" bedding them and when he must ask their forgiveness - and got it right, no matter how outlandish or cliched.
As for the Girls Club situation - no spoiler - it was merely insulting and completely unconvincing.
Acting by the two main characters would have helped.
This is easily the worst movie I have seen all year - 2 out of 10.
