I'm not a fan of revenge themes in either comedy or romance. I sort of agree with the reviewer who said you need to look at this as comedy not romance, although there is a side of romance. Just don't take the movie too seriously. The trouble is that it's hard to reconcile the two given that it's not just comedy, but silly exaggerated comedy and then the romance has serious moments. So really you have to look at the two parts differently.
There are some funny, and mean revenge plots.
