ok let us take Luke from time he boarded cloud city. At that time he was partially train. Shoot him with bowcaster and then hand totally untrained Leia a lightsaber. Who are you going to bet on winning that fight?

She’s not Leia though. She’s Rey, who’s been fighting with a staff and jumping around derelict Star Destroyers and taking care of herself with no help in a brutally harsh environment since she was a small child. Melee combat is already part of her skill set regardless of the Force.

and if I thought that, my next thought would be why haven’t we seen this “force stuff going on here that we haven’t seen before” in any of the first six movies. The first six movies make quite clear that someone totally untrained would have no chance against someone as trained Kylo Ren is in this movie.

Before ESB, there were no Force ghosts or visions. TPM turned the whole thing on its head with midichlorians. ROTS introduced power over life and death into the mix. This is how a series works. If we were stuck with only what was explicitly referenced in ANH for nine films, we’d have a pretty boring franchise.
