Since Rey’s godlike mastery of the Force is being discussed, I want to say that if there’s one thing that bothered me most about the PT, it’s how everyone goes on about how strong Anakin is with the Force, but we never see him do anything noteworthy in AotC and RotS other than basic stuff like telekinetically moving stuff around or boosting his jumps. Now I’m not saying he should have breezed through waves of enemies Force Unleashed style, it’s just that I would consider this a case of “Show, don’t tell”.
Heck, something like enhanced precognition, complete sensory awareness, or even some large telekinetic feat (e.g., ripping ships apart) would’ve sold both his status as a “chosen one” and how much becoming Vader diminished him. I don’t know if 2002/2005 CGI and physical modeling could do that convincingly, but it would’ve sold it more.
