I kinda agree with you, especially with the prequels. I like to think of them as non-canon, to the point where a reference to something from the prequel trilogy in TFA or TLJ makes me cringe. Luke Skywalker should never have to say Darth Sidious.

It was pretty subtle, but I really enjoyed to unpack all the details by myself and see a pretty powerful social commentary. I still think the more "rompy" stuff of that sub-plot worked well among the more dark and dialogue-packed Rey/Luke part. 

See, people bring up the casino area a lot. While I agree it could have been handled better, it is not even close to the worst offender to the film. No no no, that crown goes to a scene involving Leia. If you have seen the movie you know the EXACT scene I'm referring to. That made me and the entire audience go "What the hell?" -my gf was with me. She's not a big SW fan but still really liked the movie, said during the Leia scene: "Ummm.. *whispering at me* is the Force supposed to do that..?" and I went "Um. I've never seen that. But I guess..?"

That was some parody shit. I almost choked on my popcorn

That was so wrong xD. I really liked the film, but that scene hasn't really gave me a good first impression.

She's in Zero G, if you know anything about newtons third law then you'll know what she does is fine using a force push against the parts of the hull which were blown out into space.

My main issue is the scene where the mon calimari ship turns 180 and jumps to lightspeed destroying Snokes main ship at a cost of just one rebel (and a freighter completely emptied of fuel, ships and rebels) All I could think about that scene was.... "why did they wait to do it?" if the point of waiting was to get to the dark planet... their whole plan involved leading the new order right to the planet they wanted to use, one of my mates said that they waited so as to cover the fleeing transports, but they actually stated that those transports were all cloaked and the only reason the new order knew to fire upon them was the betrayal by the codemaster who informed the new order of the placement of the 30 ships so they begin firing at the space that he told them they were in.

Had the rebels launched the transports in cloak before that point then, done the 180 turn and lightspeed, they would still have lost the main ship... but they would not have wasted so much time and effectively gifted the new order the person who would betray the cloaked ships, also they would not have lost the rest of the fleet, all the medical frigates etc which were destroyed by running out of fuel and falling back into snokes ships fire... I'm sure the new orders fleet would have been a mess while they tried to work out what just happened and they most certainly would have been more worried that their supreme leader was still alive rather than go chasing rebel medical frigates or look for 30 cloaked transports heading towards that old rebel base planet.

All in all... that huge silence scene.... all I could think about was.... "why now? if you can end a chase at any stage with the destruction of the ones chasing you.... why not do it?"

The Knights of Ren did make an appearance during the making of this movie, they accompanied Kylo to the Jedi Temple where Luke was training Ray in an earlier draft of the movie, flying out on a Tie Silencer and confronting Luke before he would complete the training of "The Last Jedi" but that scene will most likely only exist now in deleted scenes.
