I just saw it, and it was amazing. Ah-mazing. No wonder it got an Oscar for best movie, it's by far I've seen in a while. The real reason I watched it was because Dev was in it, and I'd liked him in Skins. Also I wanted to know what all this fuss was about. :P
So, I loved it, no question about it. I loved the actors, the characters, the music, the scenes... everything. The story was touching, exciting, and by end I was twitching in my seat, "Come one, answer the phone, come on...". If you've seen the movie, you know what I'm talking about. ;)
On the topic of the music, I really have to say, it was spot on. Every song fit the scene, and even though they played some songs more than once during the film, it was very appropriate and nice. :)
Not really much to say really, except, go watch this movie. I mean it. It will be the best 2 hours of your life, and if it's not, you don't know real films, and to me you're on the same brain level as my little brother. So there.
