Oh dear
Sadly, this is one of the saddest things I've seen in a while. Firstly, it's just a film. Accept it.
But more importantly, if Ledger's interpretation of the Joker is so unutterably amazing that any further attempts will pale into insignificance... then surely, by definition, all further attempts will pale into insignificance. So where's the problem?
Presumably this self-appointed band of losers is trying to save Hollywood and all the world of potential viewers some appalling future two hours of watching something not-quite-so-good-as-something-else. Well, I'm happy to look after myself, thanks. No, really. Flattered and all that but I think I'll be ok. Now, off you go and play. Twats.
