These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The Scrappy: Stu has no redeeming qualities whatsoever.
Unfortunate Implications: It seems that all women want to do is get married. And since in this setting, the best way to find true love is to sleep with someone, one can kiss themes such as abstinence and Chastity goodbye. Ironically, a Christian woman was in the many sex scenes.
Not to mention that someone went as far as breaking into his apartment and attempt to rape him. Girls can do anything for marriage it seems.
There's also the scene where a lesbian has sex with him. No comment on that
As Film Brain pointed out, the fact that they played the fat woman up as being this hideous, disgusting excuse of a woman who couldn't possibly have anyone fall in love with her without supernatural means is actually a very cruel joke which implies that overweight women are destined to be forever alone. Because you know, looks are the only thing that matter about a person, right?
Why Would Anyone Take Him Back?: Cam broke up with Chuck because he was being a creepily possessive Jerk Ass. He never tries to explain himself (about the curse) - neither when she breaks it off nor when he begs her forgiveness at the end.
Not to mention that he whored himself out before, and she still took him back.
