Re: TDK's Joker: The best film villain of all time?
The Joker himself - one of the best. Any specific live-action rendition of him - I don't think so, personally. I thought that Heath's Joker was magical, that is, capable of impossible/mysterious feats and getaways with nary an explanation, whereas Bale's Batman had his every gadget and maneouver explained - it really took the edge off both characters for me. They really were opposite extremes of one another: one ridiculously capable and frustratingly unexplained [in terms of his 'abilities', not origins] and the other explained to the point of boredom [I don't really want to know how exaclty Batman knocks out electricty and plans an alibi to abduct someone - I'd rather see Batman as the villian does, as a seemingly mysterious force]. Those are the reasons I have, personally. I wasn't so enamoured by the character or his exploits.
I think A Clockwork Orange's Alex is a great 'villian', because you're made to emphasise with him - and it works!
