Just thought of another OT vs Ahsoka comparison: total runtime.
Original Star Wars trilogy: 6hrs 16min
Ahsoka: 6 hrs 2 min
Given that Ahsoka's credits and recaps probably take up at least 5 minutes per episode while the OT movies credits are about that long per movie (I also used IMDb for the runtime, so the real original OT was a little shorter), the runtime are similar.
Can anyone here honestly say they got as much out of Ahsoka story-wise as they did out of the OT? That's an awful lot of time to tell a story that had no real beginning or ending.
In the OT (give or take): Leia captured, Luke's aunt & uncle killed, Alderan destroyed, Ben teaches Luke about Force, Han kills Greedo over debt to Jabba, all three (plus droids) travel to Death Star, rescue Leia, escape, Ben fights Vader (dies), Rebels destroy Death Star, Rebels fight Imperials on Hoth, Luke captured/injured by Waumpa, Han saves Luke, Rebels flee Imperials, Han/Leia/Luke love triangle deepens, Luke trains with Yoda, Han, Leia, Chewie meet Lando, captured by Vader (C-3P0 blasted apart), Leia & Han in love, Han frozen, Luke fights Vader, loses hand, learns he's Vader's son, everyone (except Han) escapes, travel to Tatooine to free Han, Leia captured, Han unfrozen (blind), Luke helps group escape, Leia kills Jabba, Yoda dies, Luke's Jedi training "complete" except for confronting Vader, Leia is Luke's twin, new Death Star, Rebels launch 2 part attack on Death Star, captured by Ewoks, helped by Ewoks, Luke surrenders to Vader/Emperor, fights Vader, Vader turns on Emperor (kills), Vader redeemed (dies), Rebels destroy new Death Star, liberate galaxy.
Ahsoka: ...I forgot already.
(Just kidding): Sabine & Ahsoka reunited, seek and find map to Thrawn & Ezra, fight some lightsaber-wielding bad guys (that aren't exactly Sith or the Empire but aren't really explained) and some witches (also not really explained) and a smoke monster (never explained - 'Lost' anyone?), lose map, Sabine captured by witches & their hyperspace ring, travels across galaxies to Thrawn & Ezra's location, Ahsoka dies, meets/taught by dead Anakin, resurrected, Ahsoka takes space whale to find Thrawn, Thrawn revealed (returns?), Ezra & Sabine, Sabine freed (sort of) to find Ezra, fights nomads, finds Ezra, meets snail people, fights nomads again, Ezra & Sabine captured, back to ISD, Ahsoka reunited with Sabine & Ezra, witches do witch stuff, fake-Sith leader hands off reigns to fake-Sith girl, ISD jumps back to regular Stsr Wars space with Ezra, Ahsoka & Sabine stuck with snail people, Anakin smiles.
Oh, I forgot: we also learn Sabine's not a real Jedi or a real Mandalorian, while Hera flies around, disobeys orders, gets people killed, reprimanded, walks around with her back to the camera.
I'm missing stuff, but that's the gist of it. In Ahsoka, they ended up not having any real effect on any of Thrawn and the witches plans, leaving a cliffhanger and a couple heroes exchanged places, while in the OT, they overthrew the Empire and destroyed not one, but TWO Death Stars. Plus you got better character development and interaction, as well as better story and pacing, and everything was actually wrapped up by the end of the last film. Clear character arcs and storytelling.
