I’d like to see the film we thought we might get with the ST, a story about Luke set 10 years before the start of TFA. Luke uncovers a group of villains from the unknown regions of space. He (with the help of his young apprentice, Chewbacca and R2D2 in the 3rd act) are able to defeat the well armed group but something begins to change in his apprentice.
Or something involving Luke (played by Mark) set sometime between the OT and ST.
