People are going to debate the core concepts of Rey being unrelated to any known character and Luke waiting around to die for years probably, but I'd argue both of those are truly subjective debate points; its hard to argue that Johnson didn't execute both ideas in this film about as flawlessly as he could. The issues with those are opinion based analysis of the film in the context of the saga as a whole. Generally, people happy with those plot elements are capable of defending them. They're strong, debatable points...
...But I don't see anyone really staunchly defending Finn's plot among the film's defenders. And while there's a bit of discussion about merits of the First Order chasing the Resistance, there seems to be more concensus to that segment being a genuine weakness. So is it a strong argument that these elements are objective weaknesses of the film? That these elements are true weaknesses of the film?
Think about it:
- The impetus for the plot is weak in two ways:
--- Holdo, while having a point and function in chewing out Poe and being antagonistic, doesn't give any good reasons for being silent during a high stress situation where hope is key; her quote later on only obfuscates the point.
--- Holdo and Leia's plan is deeply questionable; we'll evacuate in the transports and not be seen in these uncloaked plainly visible ships. The pragmatic idea behind it is strong, but the method makes no sense when we can see Snoke can just turn on his telescope and look at them.
- The conflict and answer they come up with to drive Finn's plot (computer tracking us--> need a slicer--> go get wrong slicer--> slicer predictably sells you out) is ultimately both convuluted and useless, since the only plot impact is negative (Leia and Holdo's "plan" found out) and again, kind of pathetic (look out a window!)
- The actual setup for the chase is a boring retread of ESB's chase without any of the excitement, and is heavily dependent on both deeply questionable military lore decisions, the most egregious break from Star Wras always casual relationship with physics, and resolved by a move that begs the question "Why didn't you do that before?"
--- The physics thing is largely consistent with the space-as-an-ocean theme from the other movies, but becomes irritating when you realize the only way the "chase them but don't catch them" plot is of space somehow has fluid friction and acceleration has some kind distance limit.
--- The FO having nothing capable of catching up to, cutting off, or providing fighter support to catch the Resistance Fleet boggles the mind and exposes plot convenience, as well as unfortunately ignoring support ships that the comics apparently accidentally created that now can't be brought up when talking about the subplot.
--- The hyperspace ram is beautiful, but begs the question "Why has no one done this amazing, shield ignoring move before?" Heck, why didn't the cruiser pilots do that when they evacuated their ships earlier? Why don't people just strap engines to asteroids and shoot them at each other! Could we not set this up better?
- Great actors largely wasted by doubling up functional roles into redundancy: we have Rose, an engineer, journeying alongside BB-8, a droid like all the other magic door openers from before, yet neither of them can solve the problem, so we go after a red herring cameo, then recruit Benecio Del Toro who portrays a character so I'll-defined he doesn't have a name and only gets interesting because of the actor.
- Finally, we waste the potential and aftershocks from TFA on Finn:
--- You want to comment on the rich and powerful abusing and neglecting the poor and vulnerable? We've got a literal former slave child soldier and villains who continue to kidnap little kids to make Stormtroopers. Why the hell aren't you using that?
--- Finn was the most dynamic character in TFA by far, and exited the film having gone full hero and being rewarded with an eviscerated spine. But we barely see any reaction to that at all. Kylo gets two scenes focusing on him reacting to a cut to his face; why doesn't Finn get anything like that?
--- Finn's undercover on the Supremacy. Back in his old homeland, but with new eyes. We should see him now realizing how everything the First Order does is an insult and injury inflicted upon him and his fellow troopers. But nope! Can't use anything logical like that to give the character a righteous edge!
