* For the most part, I like this trope. When well written, it works and is easy to relate to. The one time it doesn't do it for me is when someone is a DoggedNiceGuy (or Girl) for a person who has no respect for him/her. [[FamilyMatters Quite]] [[SavedByTheBell a few]] [[TheFairlyOddparents examples of this exist]]. It's one thing to have this for a person who sees you as either [[JustFriends just a platonic relationship]] or [[ShrinkingViolet you're just to shy to approach]], but I don't see why anyone would have feelings for someone who treated him/her like dirt.
** There's actually some TruthInTelevision for this trope. Some people are insecure enough that they accept that kind of abuse and feel that they can win the person over or worse yet, they desire it. It's not as funny in real life, though.
** It's also not much fun to be on the other side - the character who is put on a pedestal and persisted after. This is why Dogged Nice Guy tropes are often disgusted as being sexist. The audience tends to side with the Nice Guy who persists and whose POV is being told, rather than the character (usually female) who becomes the object of affection.
