Vader Down was a crossover between Vader and Star Wars comic proper. (And boy could i talk about the differences between new and old Vader...)
Also you're wrong, earlier media did show just how awesome jedi could be.
EDIT: Oh I see, you said "movies" not "media" - that was my bad. I still want to leave up this kick ass scene - no matter how much damage is inflicted on Droids (seriously that clip for us is like the goriest torture porn)
Thing is, Jedi are essentially an entire class of Mary Sues which means the stories always had a problem: how do you challenge them? How do they even fall? How could anybody forget or doubt their religion after a demonstration like that?
The answer was in the book I, Jedi - where it was proposed that Jedi would have strengths and weaknesses in the Force (what made Anakin special was no weakness).
Now Disney has screwed up even more by saying newbies can be that powerful without any training. Before there was at least a chance soldiers could bring down a padawan. Now Rey does the mind trick on her first try which is a concept so horrible i still can't believe more lefties aren't freaking out (and you think it would be more so to the #metoo and consent crowd).
