I don’t know that feats of the Force have gotten more or less impressive in the ST, only that they’ve changed.
It’s true however that according to the ST you can become a powerful Force user in about a week.
Not everyone can, but Rey can, just like Luke was better than a targeting computer on a sophisticated space fighter and a child can be the only human able to pilot a dangerous podracer.
He can see things before they happen. It’s a Jedi trait. As such Luke and Anakin’s early abilities are normal for a Jedi, even if their abilities are exceptional in-universe. However, both required training to reach their potential. Rey is on a whole other level though, and masters abilities almost instantly without any training whatsoever. Two explanation are given, the first being that “darkness rises, and light to meet it”, a new concept that is not wholly compatible with what came before in my view, and the concept that Rey downloaded the knowledge from Kylo’s mind introduced in the book, an idea that negates the whole concept of Jedi training imo.
