Because sarcastic, misanthropic loner-genius characters aren't particularly a) realistic b) rare. What is complex and rounded about it? House is not a rounded character because he never develops, he just rides off into the sunset at the end of the episode. They can't make House a rounded character without changing the whole format of the show. Sure, we sympathise with him but that's because his bad traits are immediately explained away as part of his pain, or played for gags - House is a pretty shallow programme overall. Like I said, though, it's just great fun, and I love it (as long as I don't watch too much in a short space of time; it's like sweeties).
Ummm... Beethoven would have been considered a misanthropic genius. So would Van Gogh - you don't cut off an ear for nothing. Also in the show it's explained he used to act the same way before the incident with the leg indicating he's a character who has hard such a hard time adjusting to society and the fact he's in constant pain doesn't make it any better.
He does grow as a character because he becomes attached to the team as he works with them more, and although he would never admit it because of his fear of relationships and being hurt again, he does miss them and doesn't want to see them go. He just has trouble expressing himself and is a akin to a lonely, sad child. He's a realistic character in the idea of his depression and sadness, something a lot of characters on shows don't have - deep character flaws and traits. He is not shallow by any stretch.
