Basterds was fucking awesome. Jackie Brown was very strong as well. Pulp Fiction was OK, although I do think it's overrated. Reservoir Dogs is DEFINITELY overrated. Have yet to watch Kill Bill (I know, I know...). True Romance was OK as well.
OH and I completely forgot about Steven Spielberg. He is great!
Don't you mean USED TO BE great?! *Cough* RuinedArtificialIntelligencewithaliensandahappyending! *cough*
Also, from Danny Boyle, do watch The Beach. Give 127 Hours a pass. From Kubrick, you owe it to yourself to see Full Metal Jacket.
Start watching his films NOW!
True Romance was horrible. I despise that movie!
As for my favorite directors, here is my list:
Martin Scorsese
Quentin Tarantino
Christopher Nolan
Darren Aronofsky
Kevin Smith
I think Danny Boyle and David Fincher are great directors. In regards to Boyle, Trainspotting and Slumdog Millionaire were great films but I have not seen his other films yet. As for David Fincher, Fight Club and Se7en were great and although I was not that impressed with The Social Network, a lot of people do praise that film. I would like to watch more of his films though.
I would like to watch Alfred Hitchcock and David Lynch's films. They were mentioned quite a bit in this thread.
As for Stanley Kubrick, I've only seen The Shining. I would love to watch his other films as well.
Tim Burton is awful now. I thought his earlier films were pretty good but I definitely don't think he is that great.
OH and I completely forgot about Steven Spielberg. He is great!
Hitchcock I woud go with Rear Window, Vertigo, Rope, Spellbound and Psycho to start with.
