I'm surprised nobody liked the droids episode. It was Artoo infiltrating a Seppie command ship, what's not to like about that? I just wish Artoo took a more starring role.
You just answered your own question. Artoo was a bit player in a story that was mostly about two annoying comic-relief characters, the tiny colonel and the bumbling "Wac" droid that I assume we've seen before but that I'd mercifully forgotten about.
What would've been cool was if we'd gotten a whole episode about astromechs, with almost all the dialogue in untranslated bleeps and whistles. That would've been an interesting stylistic experiment, kind of like making a silent film.
