You're missing an option :
- The prequel trilogy ruined it for me.
I was a big fan of the first 3 films (especially Empire, my favorite). Then the prequals ruined it. Now don't get me wrong, I'm not some kind of bandwagoner. I actually found Phantom Menace decent (whaa... ? ). Attack of the clones was a good action flick, but somehow left me wanting. The real let down came with the 3rd movie. It somehow felt rushed and Anakin's downfall missed quite a few steps. One second he's goody two-shoes and the next he's on the dark side. Really deserved a better fall into darkness than a 3 minute scene, what happened to progression ? I know he had a few "dark" moments prior, but really, it just felt so rushed...
Then there's all the continuity errors like Padme dying giving birth but Leia remembering her mother has being sad all the time... Why would her adoptive mother on Alderaan be "sad" all the time if she doesn't have Anakin to grieve for (not being Anakin's lover...) ?
Really, that 3rd movie marked the end of an era for me. Even the originals weren't as enjoyable after that (let's face it, those movies are mostly about nostalgia, they never were as deep as we saw them with our fan tainted glasses).
