Finn was like one of the best things about the Sequels. He was an entirely original character concept. Normally, I’d be upset about how badly mishandled his character was, but since the entire Trilogy was mostly an incoherent mess, it’s kind of a moot point.

TFA set up Finn as a second main character - arguably equally as central to the story as Rey. But he was then firmly relegated to “side character” in the next movie. Finn was also obviously being setup as a love interest for Rey in TFA - (a fact that, anecdotally, I’ve found many fans strangely deny to be the case). Or at least, it was implied Finn was one side of an emerging love triangle along with Rey and Kylo Ren.

The fate of all three characters should have been closely intertwined throughout the trilogy, in the same way that the climax of TFA involved all three. Finn originally had a personal connection with Kylo Ren based on mutual animosity, which was dropped after TFA. Sadly, Finn was soon relegated to a side character and written off into oblivion. But again, why do I even care about this? These movies also have Palpatine show up out of nowhere with a secret fleet of 10,000 Star Destroyer Death Stars. At that point, it’s just Spaceballs 3: The Search for a Profitable Plot, so who even cares?
