The greatest ending ever?

[Robyn]

Well, Melancholia is (and will always be) my favorite ending ever. It's beyond great (just like all of Triers endings)

Also;

Zabriskie Point
Planet of the Apes (1968)
The Great Silence
Reservoir Dogs
The Mist
The Life of David Gale

[Jeremy Blackman]

Dancer In the Dark

[Robyn]

Also The Idiots, Antichrist, Breaking the Waves and Dogville to name a few, hehe.

[Jeremy Blackman]

Sigh... yes... but it's hard to beat Dancer.

2001: A Space Odyssey, let's be honest...

[72teeth]

LVT does great endings
Wes Anderson does great endings
Quentin does great endings and i think made my all time favorite ending with KB1, still get chills just thinking about it
Fight Club's ending, o yea
American Werewolf in London, shit chyeah
The Departed, fuck yes

Cast Away. BOOOOOOOOO!

[Just Withnail]

every single mad men

[Reel]

I'll say one thing... Rosebud

and goddamn did the end of Magnolia make me cry like a bitch the last time I saw it. Gotta have the subtitles on for that part, just beautiful. Then I cried through the credits and once they were over, started up again. Fuck that movie.

[Robyn]

Well, I laughed.

[Reel]

Yeah. They were tears of joy, like a laugh/cry. Really weird. Wish I could experience something like that at least once a week.

Cast Away. BOOOOOOOOO!

it might've been kind of a limp dick ending, but I like it. He falls in love 

[polkablues]

I know that nobody cares but me, but Waking the Dead.

Also:
Brick
25th Hour
The Iron Giant
Monsters
Let the Right One In
The Vanishing

[theyarelegion]

Carlito's Way (a six star movie)

[Alexandro]

coppola has some great endings:

godfather 1, 2 & 3 all have awesome different endings.
apocalypse now
the conversation (AWESOME ENDING)
bram stoker's dracula (surprising sad ending)

Kurosawa's Ran

Kill Bill 1 (yes)
also: Jackie Brown

PTA has the Boogie Nights and There Will be Blood endings.

2001, Shinning, Clockwork and Eyes Wide Shut.

Melancholia was incredible. Ditto Dancer in the Dark and Dogville.

Reygadas's Silent Light somehow manages to become as resonant as Ordet.

I personally love the ending for the Coen's The Man Who Wasn't There and No Country for Old Men.

The 400 Blows.

Probably my all time favorite ending for any movie is 8 1/2.

And it may not be a movie, but I think the ending for The Sopranos was a moment of true genius.

[Neil]

I am in love with the ending of Eternal Sunshine.

Seven

Naked
