My unpopular opinion on the ST: TLJ will be redeemed by the passage of time and stand out as the only worthwhile entry of the ST.
I’ve heard quite a few fans express a similar opinion. It will certainly be the most remembered and discussed (and argued about) of the three in the future. TRoS, on the other hand, will age like milk as just another forgettable holiday blockbuster. Still, there’s the issue that TLJ is the middle film of a trilogy and picks up right where TFA leaves off with its characters, so it can’t really stand on its own.
