Is it me or is parkman freaking useless, i hardly seen him fight any battles or use his power. Except the previous 2min scene where he faked Knox into thinking he burst a hole through his round belly. Unlike his father he is totally opposite of him, being so ordinary.

actually, Matt is very powerful. The bit with Knox was an incredible display of power really. But we haven't seen enough of Season 3 to see Matt utilising his full power any more. He was in Africa lazing about for 5 episodes, and since he's been back, he's done little except stalk Daphne

But I don't think it's at all fair to call him weak/ordinary/useless. The only people that could actually beat him in a fight are Sylar and Arthur (Peter would have been the third, but he no longer has his powers )

Obviously I desagree
I don't think that we have to consider "useless" a character just considering how many times he's in a fight, this is not a proper way to judge a series and Heroes is more than a simple "action seires" IMHO
