The one thing I struggle with this movie is Rey's sudden abilities with the force, and it just occured to me how they might have been able to explain it slightly better. What if, when Rey touches Luke's lightsaber for the first time, the flashback happens, then when it's over, they cut to Rey still holding the lightsaber, but levitating dozens of Maz's antiquities around her, then she suddenly realizes she's doing it, and they all drop to the floor? Then Maz is standing at the doorway, having witnessed it. Such a scene could have indicated that Rey suddenly unleashed something inside her when she experienced the flashback, which was hinted at, but was not obvious. Maybe it would be overkill, but I would've liked it.
