Okay, so Mr Kubrick is arguably one of the best directors of all times. IMDB lists his directed movies as:

1. Eyes Wide Shut (1999)
   ... aka EWS (USA: promotional abbreviation)
   
2. Full Metal Jacket (1987)
   ... aka Stanley Kubrick's Full Metal Jacket (USA: poster title)
3. The Shining (1980)
   ... aka Stanley Kubrick's 'The Shining'
   
4. Barry Lyndon (1975)
5. A Clockwork Orange (1971)
   ... aka Stanley Kubrick's A Clockwork Orange (USA: poster title)
   
6. 2001: A Space Odyssey (1968)
7. Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)
   ... aka Dr. Strangelove
8. Lolita (1962)
9. Spartacus (1960)
   ... aka Spartacus: Rebel Against Rome (USA: poster title)
   
10. Paths of Glory (1957)
11. The Killing (1956)
12. Killer's Kiss (1955)
13. The Seafarers (1953)
14. Fear and Desire (1953)
15. Day of the Fight (1951)
16. Flying Padre (1951)

Which is, IYO, the best of these? Why?
Personally, 2001: A Space Odyssey and A Clockwork Orange are both pretty much a coin-toss.
Both are incredible adaptations of the book(2001 was actually written by Arthur C Clarke alongside Kubrick creating the film), however, i think that the very last chapter being left out of Clockwork is kind of an odd choice, as i like the closure that it brings to Alex's struggle, when he comes full circle back to the violence but then grows out of it(whereas in the movie, its insinuated with his newly regained free will he chooses "ultraviolence" again and kind of leaves it there if i remember correctly).
2001 is visually stunning, and the topic matter is incredibly interesting, especially if you go on to read 2010, 2061, and 3001, but we wont go into that. Clockwork orange is visually stunning as well, but in a much different way. i can never watch this movie without feeling almost psychologically raped, its such a fucked up film. but its a good thing.
obv expecting more votes for these two, full metal, and shining, but i'd love to hear some arguments for Dr Strangelove or Lolita, maybe even spartacus.

eyes wide shut sucked

i am always raving about how awesome stanley kubrick is. in fact, just today i bought full metal jacket and made my friends watch it, and they all were thoroughly impressed.

Kubrick is by farrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr my favorite director of all time. (i know, i'm raving, but seriously, it's stanley fucking kubrick)

actually 2001 (both the book and the movie script) were written together simultaneously by both Kubrick and Clarke, with Clarke's book being more grounded and Kubrick's film being more existential and surreal.

here's my ranking:

1) 2001. such an incredible film. visually stunning, incredibly deep and thought provoking, and very very weird the first time you watch it. fav movie of all time

2) Paths of Glory: my 2nd favorite movie of all time. this is simply the best war movie ever made, and it really is not even close. it is soooo good. and the final scene in this movie is easily my favorite scene in any movie i've ever watched.

3) Dr. Strangelove. in my top 10. this is my favorite comedy of all time. it's not laugh-a-minute hilarious, but it's just so terrifyingly amusing, and George C Scott and Peter Sellers do such a great job. the final scene is insanely hilarious.

4) The Killing: best film noir/ heist movie ever. its just so damn good, and kubrick's camera usage is amazing for the heist

5) The Shining: best horror movie ever

6) Spartacus: my favorite "sword and sandal" movie. its epic. and so good. the 3 hours just fly by. and kirk Douglas is amazing.

7) Barry Lyndon: the 3 hours just fly by with this one too.

8) A Clockwork Orange: this movie is ridiculously amazing. and yet it's still ranked 8th
9) Full Metal Jacket: again, this one is insanely awesome.

10) Eyes Wide Shut: it can be a little tedious to sit through, and it may even be a little pretentious, but it really is far far far better than most people give it credit for. it is a social commentary that kind of reminds me of Luis Bunuel's later works: attack the upper class.

11) Lolita: this one is also really really good, though it does drag a bit towards the middle.

12) Killer's Kiss: this is also a very good film noir.

i would actually say that all 12 of his movies would be in my top 100.

/end bfactor style post

Was he that guy from Three's Company?

Well compared to movies as a whole obv it is a good movie. It's still a Kubrick, and the man was a genius of cinema. But compared to his OWN work, I wouldn't put it at #1, that's for damn sure.

You have to remember that the vaaaaaaast majority of hollywood films that get barfed out onto theaters in the U.S. are utter garbage. So when you compare basically any Kubrick film to the landfill that is all other major movies combined, his movies rise pretty near or at the top. But when you compare him to himself, now he's up against actual competition.

You know what I mean.

Kubrick's films are all so great that each can touch someone in a different way, and therefore I don't think it is even debatable which are the "best". Your list may be different than mine, and that's fine.

1. A Clockwork Orange. Still amazing and disturbing today.

2. Lolita. So absolutely beyond cutting edge for it's time, which is an element that made it superb...and it's a reason why the remake doesn't have the same effect.

3. 2001. Epic science fiction for its time that captured the public's fear in a very turbulent time.

With films like 2001 and Dr. Strangelove, (which I haven't seen in it's entirety), there is going to be a huge generational gap, where viewers in their early 20s simply may not understand the feelings of dispair that existed during the cold war in the 60s through thte 80s... and similary, fears about the future of technology and artificial intelligence, prior to the days of mainstream computer usage. Young viewers just may not get it, so their favorites may be Eyes Wide Shut or The Shining, or another film with which they can associate, and that is fine.

I thought Full Metal Jacket was good but I felt like it lost its momentum as the film progressed.

RIP Stanley Kubrick, an unparalleled director IMO....

My personal pavorites, without any explanations because others here have already summed them up so well:

1) 2001: A Space Oddessy
2) The Shining
3) A Clockwork Orange
4) Full Metal Jacket
5) Spartacus

Admittedly, I haven't seen most of the rest of the films listed.

Few people have seen Paths of Glory when compared some other Kubrick films, but that is my favorite film of his and one of the greatest movies of all time.
