I agree he's a brilliant actor, as I have known he's a brilliant actor for over fifteen years now (elvinborn, OMG no you DID NOT just accuse me of not knowing who he was!). But I join the ranks of several gazillion established critics when I say that Gary Oldman has been known... many, many, MANY times... to be unsubtle.
In fact, accusing Gary Oldman of being unsubtle is a bit like accusing grass of growing in an upward fashion. I'm baffled it warranted commentary at all.
He's relatively understated as Gordon, and I've enjoyed the contrast. That's the end of my sentiments on the matter. Don't poke me.
