Giving up is relative. I stopped going to see Star Wars films for myself after AOTC (and that was as a “they can’t all suck that bad!” gambit rather than a genuine desire), but I’ve seen some of the films after that anyway.

ROTS I saw because a friend had two free tickets and we had a history of going to see really crappy films together (Alien vs Predator, etc), and he wanted me to go, as a sort of lark. So I stupidly said “Sure” and man was that a step down from Alien vs Predator. We did not even get ironic enjoyment from that one.

Now I’ve got kids, and so I go when they want to go. What I’ve seen of the sequels hasn’t made me want to go back for myself, but I’ll likely go back one way or the other. Although if the sequels ever get anywhere near as bad as the prequels, I’ll probably just opt to wait in the lobby while the kids watch.
