I know I'm opening myself up to a lot of scorn here, but... I don't hate Rob Liefeld.
Now don't get me wrong! The stuff he draws is absolutely hideous. It pains me to so much as look at it. I never, ever want to own a single comic with his... "art"... in it.
And yet... and yet he's just so earnest and enthusiastic about what he does. "This guy's a big tough guy! I'm-a give him big muscles! Grrrrr!!! Ooh -- can't forget the cross-hatching!" And unlike some other hack artists (*coughgreglandcough*), he's actually fostered his own distinct style, no matter how awful it may be. And from what I've heard he's actually a very nice, pleasant guy.
I guess what I'm saying is that Rob Liefeld is the artistic equivalent of Florence Foster Jenkins. The man's a hack, but he's the best hack he can be.
