You just mentioned a couple of films in that paragraph that's going to make it to my Top 50 .
I agree that Do The Right Thing is superior work to 25th Hour, but I don't think that Edward Norton starrer is too far behind in terms of cinematic quality. The thing that makes Do The Right Thing better is it's arguably urgent subject matter.
I'm not a big fan of either Cusack or Norton either, mate. But they have managed to appear in a few great films between them. Edward Norton is a VERY talented actor, and like I said before, you can rely on him to put forward a decent performance, but he does get more recognition than he should.
Cusack works better when he's not trying so hard to be quirky. Suprisingly, he can be quite imposing when he wants to, as evidenced by his turn in Identity. Speaking of which, I know the twists in Identity may come across as obligatory and i somewhat agree with you that they are quite weak twists in that they don't really help raise the film to another level; However, I don't think that the twists weaken the film in the process either.
Overall it's a damn fine atmospheric horror thriller that I feel just has this really eerie vibe to it. I've said it before and i'll say it again,i'm ALWAYS attracted by the tone of a film, and Identity provides a tone that is more than appropriate for the film. It's got some moments of unbearable tension, and the fixed shot compositions are reminiscent of Hitchcock. And that's as ultimate a compliment I can give this film.
As for Haute Tension (Switchblade Romance in the UK), I think it's a brilliant twist!! I was in complete shock and literally said 'hold up sec, bruv' as I came to the realisation of what was happening. Sure, the twist exposes a lot of plotholes, but it still took me by surprise.
But I really am interested to hear what you think of Eden Lake . That's got a Switchblade Romance vibe to it and I really don't think you'll be let down, mate.
