One of the most immediate questions I had, and there are several: Why the fuck didn't Ren just paralyze Finn? Done it to other people, hell, did it to a laser bolt. Because we needed a lightsaber fight? Why? Freeze the man, take the saber and kill him while you're at it. Completely missed that opportunity for making him appear more evil than what they tried to do on the bridge, because that scene with Han? That was trash. Screenwriting straight out of the prequels. They also just took a shit route with the Star Killer base. It took a huge chunk of time for a plot element that was just way too similar, and didn't have any depth or feeling to it. "Ooooh! So evil! It's never been done before!" The charisma that Poe had earlier just straight up died in those scenes in the fighter. Another throwback to the original series, I'm sure. They had every chance to interject some pilot banter, and all we got was dead voices. And what's that? Why certainly we'll add in a fascist speech to make the First Order seem sinister. To hell with super weapons, to hell with failed opportunities for an actual good story, to hell with the majority of that movie.
