I bought the DVD a few times and I have also come to appreciate and enjoy this movie more upon repeat viewings. The Canto Bite/Casino act is still useless though. :/

Thoughts...

* Bombs dropping in space - scientifically accurate! Simply put, this battle occurs above a planet where the Resistance Base was. Thus they are still within relative influence of that planet's gravity. The ISS is also still within influence of the Earth's gravity, as is our moon. The ISS remains in orbit not because it's weightless but because it's in perpetual free fall due to its sideways momentum, creating what is known as microgravity. If the ISS were to ever stop moving then it would plummet to the Earth, which is what happened to the old Mir station. As the bombs dropping on the Dreadnaught are only moving downwards, they do not have sufficient sideways momentum to generate microgravity, thus they would indeed fall to the ship's surface.

* Resistance ships appearing to slow down after running out of fuel. This is criticised because in a vacuum, an object should continue to be in motion unless acted upon by another force. Running out of fuel doesn't slow a ship down since there's nothing like gravity or atmosphere to act upon it. However what we are looking at here is relative speed. In order for the Resistance ships to be burning fuel to outrun the First Order, they would have to be accelerating and not moving at a constant speed. Once the ship runs out of fuel, it ceases to accelerate. The First Order ships on the other hand are still accelerating, as are the Resistance ships which have yet to be fuel depleted. Thus the depleted ships would appear to "slow down" relative to the First Order and Resistance ships that are still in acceleration.

* Rey being a nobody: this was deliberately done to make her new and different! Making her related to someone else has already been done and is still being done. Luke was Darth Vader's son and Kylo Ren is related to Luke, Leia and Han. When a protagonist is related to other characters, especially the antagonist, then the stakes are higher. They are bound to these other characters. Darth Vader was no longer just some masked bad guy that Luke could blindly hate, he was his father. He was part of himself. "I cannot kill my own father." -- there's a dilemma here. And we know that this dilemma still exists for Kylo. Killing Han was a difficult decision to make, and we know that Ren couldn't bring himself to kill Leia. Rey is a completely different concept. Here is a character with no ties to any of the other major characters. This then makes her motivation arguably more pure. She is not under any real obligation to thwart Kylo Ren, and she could choose to join him or just walk away from all this if she wanted to. This is not her fight, so to speak. But the fact that Rey chooses to continue to fight for the Resistance even after discovering that her parents were nobodies demonstrates an additional level of determination and moral resolution beyond that of even Luke Skywalker. She's like Wonder Woman in a way... she just wants to help people and do the right thing.

* Luke being the fallen hero. Again, this was done to make something new. Luke needed to be a mentor for Rey, but Rian Johnson has made the decision to make him different from Obi-Wan Kenobi or Yoda. In his youth, Luke listened to his friends crying in pain and flew off the rescue them despite Yoda and Obi-Wan's warnings. And his friends suffered as a result. With the rise of Kylo Ren and the First Order, Luke can also hear voices crying for help again, but coupled with the personal shame and guilt that he felt, he also remembered how he made matters worse the last time he listened to this instinct. Luke has isolated himself and severed his connection from the Force in order to protect others as he has come to believe that the Jedi are just as bad as the Sith. He believes that his further involvement will only make matters worse, not better, and thus the best he can do is stay away. Ultimately Rey and Yoda teach him that this isn't true, but we can understand why Luke has fallen to this level, and it also gives him a journey to complete on his own.

* Kylo the rage monkey -- I forget how young Kylo is supposed to be. Both Rey and Kylo Ren represent youth, with Rey personifying hope and Kylo personifying anger. He is the Yin to her Yang. And we see in the throne room battle how the two working together can achieve a balance, even if it was just temporary.
