They don't need to be Classics necessarily. Just good. Which is why I would throw in the Xmen and Spiderman trilogies (assuming the last movies in each fit as a complete trilogy and are good individually). I'd probably throw in Blade also just because 1 and 2 were pretty good, and 3 was meh, but still fun.

But you're right about The Matrix. I would only watch it for the first one so it probably would get thrown out.

Alien Trilogy is definately up there. I still liked Resurrection, and thought AVP as...ok.

And OMG I can't believe I forgot about the Evil Dead series.

Speaking of the Mariachi trilogy, I hadn't actually seen "Mariachi" up until a couple of days ago. Very interesting. I was kind of taken back by it after seeing Desperado/OUTIM already, but it wasn't too bad.

Oshits, and the Batman Trilogy. I say trilogy because "Batman and Robin" is basically Batman on Ice. Good job Schumaker with the flamboyant colors and nipples on the batsuit.

Can't wait for Batman Begins.

Which 2 of the Superman Quadrilogy does everyone consider to be good? I liked 1 and 2, and can't even remember pt. 3, other than it was about him fighting himself and a computer. 4 was bleh.
