What is the best trilogy of all time?

In terms of full quality of three movies combinated:

1. The Three Colours Trilogy
2. The Before trilogy
4. Star Wars trilogy episodes 4-6
5. The Dark Knight trilogy
6. Dollars trilogy
7. Lord of the rings trilogy(bit skeptical here since I really don't like lotr)
8. Godfather trilogy
9. Back to the Future trilogy
10. Vengeance trilogy

Toy Story,Die Hard,The Terminator,Indiana Jones arne't trilogies ANYMORE.
Also The Godfather and Dollars trilogy are perhaps best trilogies with first two movies being clearly better than other. Problem is 3rd movie is not on same level. Especially Godfather 3.

Me, myself and I. Best of all time!

Some of those you'd have to pay me to watch:

Godfather trilogy
Spider-Man trilogy
The Dark Knight trilogy
The new planet of the apes trilogy

It's gotta be Star Wars.

It reached the most people.

My favorite is the Ingmar Bergman trilogy of THROUGH A GLASS DARKLY, THE SILENCE and WINTER LIGHT. I saw them all at once on a night I will not forget.

Hmm, I have to go with the original Star Wars trilogy, although that one's far from perfect.

RESERVOIR DOGS

1. Star Wars (4-6)

2. Lord of the Rings

3. The Godfather
