The Godfather Trilogy by far. Even with the lesser Part III. I love Star Wars and Indiana Jones... but the Godfather was on a whole different level.

Evil Dead Trilogy was a lot of fun too.

Unpopular opinion: Indie 3 best Indiana movie

I would say the Spider-Man trilogy but it has its flaws klike the constant screaming women, the fact that those movies became the cliché of what a super-hero movie looks like (the hero gains his or her abilities, have a love interest, a vilain appears or gains its abilities too, and they fight, most of the time in front of the love interest), or the really bad depiction of Venom by Sam Raimi who didn't like tye character (and who always been a favourite of mine).

Same for the Matrix trilogy too. And also Matrix Reloaded reminds me the death of Michael Jackson, since I was watching the movie just two hours before his death was announced, and was interrupted by the megavideo limit of 52 minutes. This has nothing to do with the quality of the trilogy, but I can't enjoy watching it.

Since Star Wars is an hexalogy, I can't put it here.

Never watched The Lord Of The Ring, I was more a Harry Potter fan, so can't put it neither. Nor Indiana Jones.

So I'll just go with the Iron man trilogy. Always fun to watch rich people fighting each other for make more profits

I agree! The first one is always hard to top, but at least the following movies do change up the subject sufficiently enough.

Wait u include starwars, but not films like indiana jones, why is that?

I’d actually say you miss too much by watching just the theatrical cuts. And that Return of the King actually benefits the most from the extended editions instead of the other two. In it, there’s a couple plot-points that get wrapped up less rushed and more satisfactory. Can’t really go wrong, but I’d pick the extended editions.

I’m just glad they skipped the whole Tom Bombadil part from the books.

I haven't seen every notable trilogy listed, but I'm leaning towards Star Wars.

Maybe Back to the Future, but I have to rewatch it. Its been a long time.

Good call, but you can get an even greater Sergio Leone trilogy if you take Once Upon A Time In The West, Once Upon A Revolution (known as A Fistful Of Dynamite) and Once Upon A Time In America.

I'm really surprised at how unpopular The Godfather seems to have become ... although someone mentioned it as their choice I was the first vote for it. Either people here are just too young to rate it or they really hate Part 3.

Die Hard should count because it existed (and was marketed) as a trilogy for a long time before 4.0 was made. It shouldn't win though: the second film is weak and the third only average.

LOTR. One of the few franchises that could coax me into going to see them on the big screen, and it was totally worth it, even with the little kid beside me who kept asking what was going on every 5 minutes during the second one. Not, short, movies. His father and I had a 'friendly' chat afterwards and I immediately understood why the kid was like that.
