Yeah I went to see Sweeny Todd with the missus when it came out, I have to say I wasn't overly impressed with it, but she loved the film so brownie points for me
It was all a bit musical for my tastes and not really dark enough (never thought I'd say that about a Tim Burton film!) although Sacha Baron Cohen (aka Ali-G) was extremely funny in the film.
Someone mentioned "No Country For Old Men" by the Cohen Brothers in this thread, now that is a great film that I really enjoyed, however the ending wasn't what I was expecting (not going to say anymore).
Javier Bardem (the main 'bad' guy in the film) was excellent, a really creepy character portrayed excellently, I'd never heard of him before this film and looking through other films he has done I'm not surprised, just check out some of these titles "Between Your Legs", "Trembling Flesh", "Mouth to Mouth", "The Tit and the Moon", "Not Love, Just Frenzy", "Golden Balls" and my personal favourite "A Tale of Ham and Passion".
Need I say more...
