I think I best summed it up in a post a while back
Imagine you are watching Star Wars circa late 70’s…Cantina Scene
Luke Skywalker crosses over and starts talking at the bar. There in the back for a brief but noticable flash is…The Osmonds decked out like space pirates but recogniable with their brilliant smiles.
The role of this movie series for some is to separate reality from fantasy. This is supposed to happen a long long time ago in a galaxy far far away…so why should serious fantasy goers have to even stomach a microsecond of the ‘flavor of the month’ in boy bands?
Star Wars is in some minds the pinnacle of ‘serious sci fi’ in movies (and yes I know 2001 and such but like I say - some) and throwing stuff like them in the habidashery is akin to having C-3PO say something like “Is that your final answer?” for cheap (and I mean CHEAP) laughs.
Lucas I believe recognizes this (hey…he must have after the INFAMOUS Star Wars Holiday Special with the ‘groovy’ sci fi stylings of Jefferson Starship…but I digress) and when word leaked about N’Stink becoming victims for a grand second BUT becoming Jedi, every fanboys secret wish, and the ire flooded back at him, he took em out.
You don’t fuck with a moneymaker…and he nearly lost them with ol Jar Jar.
But thats IMHO
Besides, you read any Jedi tech manuals they regular post out? They got backstories to every character - dead or alive - Imagine them trying to come up with ones for the fruitballs and making in Star Wars canon.
