At least until a couple years ago most people here would tell you ROTS is either dead last or second to last in a “Best To Worst” list, but I think the tide’s shifting even here. ROTS is almost universally acclaimed everywhere else in the fanbase though, and, anecdotally, most peoople I know, be them fans or not, think ROTS is not only the best movie in the PT but the best movie in all the saga. It’s not too unusual an opinion anymore.
Still, as shown above, many here still strongly dislike it. I don’t feel too strongly about it, I just like it. But I think it’s worth pointing out that there’s many many people nowadays who really love it.
