Movie series where just the 1st one (of 2, 3, or more) is good enough

[Jmobie]

Are you like me? Do you feel pressured sometimes to purchase the entire set, when you know you only cared for the first movie in the series?

I am debating whether to get the entire Matrix and Pirates trilogy. I already have the Matrix trilogy on DVD, and I know even just one would be fantastic on Blu-ray. I actually only cared for the original Matrix. I recently saw for the first time POTC1, and apparently the next two aren't as good. I'd rather put the money into series I really like, like Bourne or Band of Brothers.

Have you purchased, or are you planning to purchase, just the 1st one in a movie series?
