A rather perplexing film.

Rating: 6/10 (16 December 2017)

MAY HAVE SPOILERS, IF NOT ALREADY MENTIONED.
Okay, let's get this out of the way: I do not hate the Last Jedi. I do not hate any Star Wars film - Even Attack of the Clones, my least favorite movie in the franchise (I gave it a 3/10 on this site), I merely dislike. (There's a difference.) I also quite like The Force Awakens, even though everyone on the internet loves to crap all over it.
That being said, I was rather let down by this movie. While I applaud Rian Johnson, the director, for having the guts to take the franchise into new areas, I feel he screwed with Star Wars lore a bit too much. For instance, I'm not entirely sure if the Force works in the way it is depicted here.
I also did not like what was done with certain characters. Leia has a moment where she is in space, and she uses the Force to get somewhere. Now, I know she theoretically has the ability to use the Force, her being Anakin Skywalker's daughter after all, but she didn't learn to use it, as far as we know. Even if she DID, it came out of nowhere. This trilogy, sad to say, has no problem with overpowered characters. (Yes, Rey is still a little bit OP here, but it's handled better than Force Awakens.)
Also, Luke was quite the sourpuss in this movie. I'm sorry, but that's the best way to put it. Yes, he was probably broken by what happened with Kylo Ren, but I'm not buying it. I won't say anymore, since I don't want to give away too much, even though this is a spoiler review. I will say, though, he has a really cool sequence towards the end of the movie. But, what happens in his arc later did not sit well with me.
And yes, the Finn & Rose subplot was completely unnecessary. If a few certain characters didn't screw around did what they were supposed to do, we could have dropped this whole subplot and shaved off 45 minutes.
Lastly, this movie also did injustice to 2 characters, namely Snoke and Admiral Ackbar.
MORE SPOILERS BELOW
First off, regarding Admiral Ackbar: We all remember this dude and his "It's a trap" line from Return of the Jedi, right? He's rather well known. But he gets killed in this movie in a spaceship blast, unceremoniously. WTF?
Next, regarding Snoke: We waited, for 2 years, to know more about a character shrouded in mystery. But nope, Kylo Ren just decides to just kill him in a move that makes no sense to me.
This movie isn't all bad, though. The acting is solid, the score is brilliant as per usual, and the movie looks GORGEOUS. The story just disappointed me.
If you're a casual Star Wars fan, or if you're not even a fan, you might like this one more than I did.
Adam Driver said that this movie would be the Empire Strikes Back of the trilogy. One thing to note - that one initially perplexed people when it came out, just like this one, and is now regarded as the best Star Wars movie. I do hope the same thing happens here.
