You have to see some of Jacksons earlier works as well as Braindead and Bad Taste are simply sick and great.
I don't like horror movies, but i appreciate his use of camera work in the LOTR trilogy.

I like some of Finchers work, Seven and Fight Club being my favs, i also enjoyed the Game, quite a clever film.
I freaken love everything about Fight Club. The cinematography, the editing, the CG techniques(that look very realistic might I add), the direction, the acting. Not one thing went wrong. I liked Seven a lot, it was very dark. The Game was good, but it had inconsistences that came with the script, can't really blame the director.

PT Anderson? I only enjoyed Boogie Nights, he did magnolia as well didn't he? Not my cup of tea to be honest.
I have yet to see Magnolia too, very soon i will. I liked his camera work in Boogie Nights. The character development was excellent as well. Overall it showed real talent.

BTW may I recommend you watch Wong Kar Wai films. He's an amazing director. You might not like the love stories though, so I don't know.
