Awesome read so far!! Just what I wanted: debate on everything from what is a good trilogy to whether or not it's complete.
One that I told Snowman I left out (but didn't feel too worried about) and nobody else has mentioned either is the last Spiderman trilogy. Btw, what about American Pie, American Pie 2, and American Wedding? I'm choosing to ignore the ones after that except possibly American Reunion (I haven't seen it yet).
The most interesting thing I find is that, w/ very few exceptions, it's hard to get 3 movies right in a row.

PS- Jeff thanks for bringing up the older movies. I want to check some of them out, especially the Sherlock Holmes ones.
