For me it's not just one event or character, to put it simply it's how good the good guys are and how bad the bad guys are. It doesn't necessarily 'break the enchantment' but it is something that affects my appreciation of the 'secondary world'. It's also why I find characters like Feanor, Eol and Gollum more interesting than Finrod, Galadriel and Sam and can't stand the Vanyar.
