I just got back from watching The Last Jedi, and overall, I did like it. I can see why it's controversial, mind, but I seem to be tending to the liked it side. I'll have to rewatch it when it's out on disc to see if my opinion has changed. But for now, overall positive for me.
I will say I did see some parallels with V and VI, namely the rebels being at their lowest point, as was in V. And the scene where Ray, Kylo and Snoke are discussing does have a few parallels with the original confrontation in VI. All in all though, it felt a lot more unique, even with these parallels, compared to Force Awakens. I also am a bit bemused with how they defeated the First Order fleet. If they could do a kamikaze hyperdrive attack, why didn't they do that sooner? Though I guess you could argue that it was a risky manoeuvre that wasn't guaranteed to work and was done as a last resort, but still, hmm.
Something which I did appreciate was how they included a locale which felt more shiny and akin to the prequels, as opposed to the industriousness or ruggedness of the OT. I really liked the look of the Casino area, even if I did find the subplot there to be a bit drawn out. Also enjoyed the Yoda cameo, though it's a bit odd seeing him as a puppet again after having seen him as CGI or animation of recent times. Space battles were also nice to look at, though that's something which I don't think Star Wars has ever really faltered at.
Didn't like how prominent characters like Phasma and Snoke were killed off with very little fleshing out on their stories. Snoke in particular given how he's clearly a proficient Dark Side user, I don't think we've seen Force Lightening in the sequel trilogy until he used it very briefly. Hopefully there will be some supplementary lore on them, but it'd been nice to know a little more. I also wasn't too enamoured by the new main character, Rose. She wasn't bad, but I didn't feel much for the character, and if the ending is anything to go by, I'm somewhat worried that they're setting up a love triangle situation with her, Rey, and Finn. I'm not against such scenarios, but they can often be rather cringeworthy to go through.
