None. For me anyway. I always thought he was overrated. This guy did everything he could to hasten his own demise. Fortunately, it appears anyway, he cleaned up his act. Then, the stroke of luck captured him in the form of "Iron Man". He's been riding high (figuratively, not literally, LOL) since. But in terms of pure acting ability, he's ok, nothing special. And top roles? I can't think of one.
