A lot of these choices seem to be votes for the WORST actor. Most of them haven't ever really been "overrated". I'd go along with Cage, he is terrible but seems to be quite well-regarded.
Two things that made me laugh - that James Nesbitt plays an Irish-sounding Roman in The Passion; yes, well that's much more absurd than all the English-sounding Romans and Judeans in that programme isn't it? And to criticise Kidman then say "give me Al Pacino anytime"? At least she plays a wide variety of roles. I heard recently Pacino's going to be playing... guess what... a cop. Oh, really? What a departure! I do agree though Kidman's a bit technical - for me a bit like listening to a virtuoso Clapton guitar solo. I can see the technique and skill are there, but it doesn't move me.
