But that's kind of like saying "a black guy mugged me, I hate all black guys now".

I'd really prefer anything that takes the "I'm so perfect" shine off of elves. It leaves such a bad taste in my mouth.

In any case, people don't like nitpicking because it sounds like you're trying to tell people they shouldn't enjoy a movie. It also sounds pretty snobby, as if you think you could have done better by staying truer to the source material.
