Now that luke vaporized into thin millenial air, Rey will have to resort to youtube videos to learn the craft.
Star wars geeks have already suggested the Jedi books were stowed on the falcon. Perhaps... Blah blah blah....
I can suspend disbelief all day long (guardians of the galaxy is a good example- "hey look, a talking raccoon" - just fun science fantasy where anything goes), but suspending disbelief for the sake of lazy story writing is a whole different issue.
When movies of this magnitude come along, I think they needed to finish the script, set it down for a couple of weeks, and then come back to it with fresh heads.
In MY script- Rey turns to the dark side in VIII (while with Kylo and Snoke) and the movie ends, not only with the rebels effectively destroyed, but an evil Kylo, Snoke, and Rey at the helm. That would leave a very dark ending that would have disney execs trembling.
Rey then would go on to kill Luke herself in the beginning of IX. Infact- with TABS like confidence, I've got a rough outline of IX in my head already, which would kick the crappola out of whatever they will cobble together in the next movie.
Disney wouldn't like me for one minute!
