First, to answer the "fake" question:
Yes, I know that the winner of the match is already known before the match begins; and that they aren't really beating the crap out of each other. Those are the ONLY two things "fake" about wrestling... these guys really can (and do) get hurt.
I like to compare wrestling to watching a stunt in a movie, or watching a magician's act... you know what you are seeing isn't really what's happening, but the good ones make you doubt yourself and you sence for what is real.

As you can see, most of my favorite wrestlers don't have (or need) a "gimmick"... They get into the ring and just give the fans one hell of a match. This doesn't mean that I don't appreciate a good "gimmick" (or a good character)... as the following list should prove.
