Right now with only seeing ROTS once, this is how I would rank these movies:
Well, nothing can beat ESB, I don't care how good ANH, ROTJ, or ROTS are, that will always be my favorite. And in my eyes always had the best production quality.
ANH was where it all started, and was an astounding movie as well so that's an automatic second.
ROTJ was a really good movie and so was ROTS. ROTJ was much lighter, while ROTS was much darker. But both had their flaws IMO.
I think I need to see ROTS again to determine if it falls above or below ROTJ. Right now, I'd say their both tied. Just my opinion for only seeing it once, and I'm wearing my flame retardant vest while saying it too so flame away.

TPM and AOTC fall under the poop category, at least the unedited versions. But even with the edited ones, they still rate very weak. I guess I'd rank AOTC better than TPM. I doubt I'll ever watch an unedited version of these movies again though.
BTW I voted very good, because it definately wasn't perfect.
