After taking a few days to mull over it more and talk to some friends on their takes of my gripes with the movie, I am still pissed with the general slow car chase in space, but I think the Yoda line of "failure is the greatest teacher" is much more the overarching lesson of the movie.
Literally everyone is making difficult decisions in difficult times and they are all failing, badly. But that the people making those decisions (especially after Snoke gets run through and Leia is unconscious) are in general young, or relatively inexperienced in positions on authority for both sides (Resistance and First Order), and I think that was the point of most of it. Kylo is super young, Hox or w/e isn't that much older, Finn/Rey/Poe are fairly young, and even Purple hair was a leader, but clearly in a subordinate role until called up.
I don't care about how/when Luke "dies", Rey coming from nothing, and while I wish I knew more about Snoke dying, I am kinda glad that potential loose end is done.
Going on the bombing run, I thought it was weird, no way that ship has enough gravity to pull them down towards it that fast, even a very big ship like Snoke's is still (and I looked it up) 60km in width, huge yes, but tiny compared to any planet or moon, let alone that deadnaught. I chalk it up to some sort of unseen propulsion at work. The bomb doors being open and her being fine is really no big deal, literally since the beginning there have been examples of what I am assuming big force field containment (see Millennium Falcon going onto the Death Star).
