uhh, the old movies did that too

What do you mean?

Luke had established himself as a good pilot multiple times in dialogue, and he never used the Jedi Mind Trick until Return of the Jedi, and it's implied that there's a long time gap between Empire Strikes Back and RotJ in which Luke completes his Jedi training, even constructing his own light sabre

thats exactly what i mean. it does the time skip in all the movies.

But I don't think that's what punisherswar meant.. I could be wrong here, but...

Finn sees his first combat ever --> he's now capable of pulling off a successful escape in a devastatingly well-armed fortress literally minutes later.
Finn has presumably never had any experience with a blade-style weapon --> his first fight is successful with a light sabrealbeit just barely
Rey finds out the force is real --> 10 minutes later of screentime and presuming she's never once attempted using the force before, she's reading Kylo Ren's mind (and preventing the vice versa through willpower, apparently)
Kylo angrily leaves the interrogation room and allows Rey to be guarded with a soldier --> Rey can suddenly pull off a Master-level Jedi Mind Trick on her second attempt at it

The Original Trilogy didn't have this kind of rapid progression. Luke finds out about the force, he's terrible at it until RotJ... Remember it took every ounce of his concentration just to move his light sabre in the ice cave, and even then that's with Obi Wan's guidance.

There were few major time leaps, and the few they had were well implied, except perhaps for Han Solo and Leia's imprisonment on Cloud City.

That would make sense since she is pretty obviously luke's kid. which would make anakin her grandfather, and the face genetics could have skipped a generation.
