As an average sci-fi fantasty film, it was entertaining, but forgettable. As a Star Wars film, it was atrocious. This was not Star Wars.
A major part of Luke's heroism is searching for the good in people and trying to bring it out of them. As everyone else gave up on Vader, he didn't and he risked his life for it. This search for good in others is engrained in his identity.
The people who made this film had zero understanding of that. Luke would never have held a lightsaber over his nephew and insist that he's not redeemable, especially since it was obvious even to this random girl Rey who could sense that he was conflicted. But somehow in the years since ROTJ, Luke has turned into a homicidal maniac who considers killing his nephew while he sleeps.
While I found Luke to be the most unsettling part of the film, there was plenty more nonsense throughout the rest of it. The plot line of the First Order holding back from attacking the Resistance ships was such incredibly lazy writing. How convenient for Finn and new girl to go to the casino city, get arrested, break out, and sneak on a star destroyer all while the First Order is still slowly pursuing this Resistance ship. The entire time, all I could think was, why the heck aren't these guys attacking this ship that isn't going anywhere? They already sent out Kylo and some other TIE Fighters to hit the bridge. This made no sense. Did that whole plot line with Finn and new girl in the casino even serve a purpose considering they were caught and there was a ship that rammed into the star destroyer in the end? It was all pointless in the end. Nothing came from it. Same with Poe's mutiny plot line. Outright pointless, nothing came from it as he was stunned in the end and woke up.
The Throne Room scenes had lines that were taken almost verbatim from ROTJ, all the while I kept thinking, "Haven't we already seen this scene?" How is Snoke so powerful too since not even Palpatine, the ultimate Sith lord, could do what he was doing? Guess we'll never know as they never bothered telling that story. Palpatine was the head of a fascist political Empire, but what exactly is the First Order? They're not a government, so how in the world do they get any money or support for what they do? Again, no explanation, so it gets pretty hard to care beyond just an artificial label of 'bad guy'.
The over-the-top uses of the Force were absurd. In the OT, the Force was subtle and mysterious. In this film, it was a joke from Leia to whatever-the-heck Luke was doing at the end telepathically dying. I like Rey and Kylo communicating with each other through Snoke (yet again, how does Snoke even know how to do that considering the Sith are dead? Who is he?), but then the awful self-aware humor throughout the film had to ruin those moments too from the dumb shirt joke to "I don't feel like talking" or whatever similar thing he said.
