The original trilogy was awesome because George Lucas did not have full creative control. The editors (Paul Hirsch, Marcia Lucas and Richard Chew) prevented a new hope from being a complete dumpster fire. The prequels had too much George Lucas, and the sequels had too much ... I dunno? Decisions by managers or something?
Anyway it seems The Mandalorian was awesome because it was a passion project by true OT fans. The franchise needs to wait for that type of project instead of just green lighting half hearted crap by folks trying to extract value out of star wars.
