Having watched the film again today, I still am struck by how the biggest event that felt out of place was the reveal of Luke. The film would have been much better if they had cut to credits as Rey makes the jump to lightspeed.

The staircase with twirling helicopter shot felt so out of place.

On further viewings, Harrison Ford didn’t seem so old. The pacing actually seemed much quicker. The Rey duel with Kylo seemed less unrealistic and more inspiring. The only thing that still seemed completely ridiculous was how important the captured Resistance members were (Poe/Rey) and how they were both being guarded by exactly one First Order trooper each time.

Things I had never noticed before:

The troopers searching for Rey/Finn/Han/Chewie said “We think they’ve split up” ala ANH
Finn crashes on Jakku and as that is happening, Hux says to deploy a detachment to look for the escapees. Finn then proceeds to walk across the entire friggin desert and makes it to the outpost before the FO arrives.
Kylo does seem to know who Rey is from the very beginning.
