Unusual looking.....
He has an unusual, bug-eyed look to him, but when I think about it, I'm glad that he looks the way he looks and not like every other Hollywood actor.
Frankly, I'm over the Zac Efron/Taylor Lautner Ken-Doll stereotypes. They get annoying after a while because they expect their looks to account for their shortcomings at being actually able to act.
Jeremy Allen White on the other hand is a nice change to see around, a more relatable actor and a better one too because he actually puts himself into his roles (I've only seen Shameless, but I'm guessing he'd do the same all round) and takes on a role with a lot of grit behind it. And the result is that even though I personally didn't think he was a good looking guy at first, I realise that "what the *beep* does that matter?" because I'd rather hang around with him then hang around with pretty-but-stuck-up-dicks.
Kudos to the people behind Shameless for their AMAZING casting!
