0. I'm an old fan. My 6 year old butt was in the seat for Star Wars in 1978 in Muskogee, Oklahoma.
1. I love all new Star Wars movies equally. I love Epsiodes 7 & 8 as much as the two stand alones.
2. I dispute your notion that the stand alone movies are getting canned. I have not seen any official reputable source who has said anything of the kind. Actually, they've said the opposite. I would expect it is more accurate that they are reassessing:
a. Their director selection process,3. Even if they were getting canned, you cannot fathom why the movies that made more money are being kept by the studio, and the movies that made less are the ones being "canned?"
b. How much they spend on each movie,
c. The release schedule.
I didn’t mean from a business perspective, I meant more along the lines of I can’t believe the trilogies are more popular.
