So to sum up in one sentence what I thought about this movie: It was fun, you should probably see it, but I do have some grievances.
Now that we've done the tl;dr version let's talk spoilers and opinions, so if you have not seen the movie either go see it, stop reading, and/or keep reading at your own risk.
My opinions on this movie are odd. I personally thought it was a fun movie, probably my favorite of the new Star Wars movies so far but I don't really like the direction they're going. The movie itself was fun for the most part but the way they handle Luke and really the Jedi as a whole in this movie doesn't really make me optimistic about the 9th movie.
I liked this movie's fight scenes for the most part, the Rose and Finn part wasn't too great but the space battles and the Resistance base fight was cool. The spectacle was fantastic, and the maneuver with the cruiser was awesome. Even Rey and Kilo's fight scenes were great. So in terms of action scenes, it did its job quite nicely in my opinion.
As for my dislikes... The Finn and Rose subplot wasn't horrible, but it felt preachy. Maybe I'm overthinking this too much, but it seems like movies anymore have to have some message before having any story, or maybe as one person I know put it, "We go to the movies to be preached to and church to be entertained anymore." That kind of is how this movie felt to me, it seemed to be saying, both the Light side and the Dark side don't have it right so we should just destroy their doctrines and make our path, that's what the force really wants. Perhaps it's just saying that there's good and bad to both sides and no side is perfect? I guess it depends on what happens in the next movie, I could've sworn I saw the Jedi books (the ones thought destroyed) in the drawer of the Millennium Falcon when someone grabbed a blanket so maybe it's not saying what I thought. However, I think that Luke's death was ok in terms of the movie, but the death in itself was what bothered me. It seems to be continuing a trend in these movies, let's kill off these main characters and let our original characters play Star Wars now guys. I mean there's passing the torch to the new people versus torching the originals and having the new characters walk over their remains.
I'm sorry I gotta rant about something happening since Episode 7. How is it that Rey, with no Jedi experience or training can mind trick a storm trooper, grab a lightsaber from someone else's grip, but Luke, a Jedi master, has trouble with Jabba and Qui-Gon has trouble with Watto? Luke pulling the lightsaber to save himself in Empire Strikes Back makes sense. Pulling an inanimate object shouldn't be too difficult especially since Obi-wan gave him some basic (granted very basic) Jedi instructions and I think Luke had some significant time between the Death Star blowing up and ending up on Hoth. It wasn't like episodes 7 & 8 where each movie takes place with 30 seconds of each other, Rey hasn't had much chance to do much else other than find Luke. I mean even Anakin, he was basically made of pure force but the best he could do was pilot ships with very good reflexes, like Luke without any Jedi training. I mean I can accept Rey adapting to piloting the Millennium Falcon, the repairs to it (she was a scavenger and probably helped repairs ships some I'd bet), but mind tricks and force powers? And by the end of episode 8 you got 7 year olds pulling brooms with the force?! Unless the Jedi ghosts are appearing to random people and teaching them random Jedi tricks or if somehow because of the lack of Jedi and Sith the force is much quieter (kinda like how if there's less people using the internet you can go faster on it and it seems better) and has a will of it's own then I'm clueless.
As a whole, I'm slightly frightened by the direction they seem to be taking Star Wars, but as for the movie itself, The Last Jedi was fun.
