I would have to say
The Big Lebowski.
Maybe the movie wasn't really underrated, but still, I must have seen it, what, 3-4 times now (which is quite a lot for any movie in my case) and it keeps getting better.
John Goodman is simply perfect. He is so...
Then Jeff Bridges. The Dude. He makes you laugh and cry. Not to forget Steve Buscemi. 'Shut the **** up, Donny.'
This movie... it transports me to somewhere.
I mean, the shot where the Dude is on his rug listening to bowling noises.
Or the dreams he has, these three guys with big scissors running behind him. That is some classy stuff.
Or them scattering Donnie's ashes.
This movie is definitely underrated. How many Oscars did it get? That's what I mean.
