I was actually hoping for 4 seasons. Considering how they put 4 different, excellent stories in season 1. Season basically told a single story (the Ghorman massacre) spread out over 4 years. There were many moments where I'd hoped they'd dive a bit deeper into some other aspects, like what would become of the Maya Pei Brigade, the stolen TIE Avenger, other missions where we see Andor grow into the expert spy that he's clearly become. And of course more about how they bring the various parts of the rebellion together, the move to Yavin, etc.

I think there was more than enough room to fill at least another season. Maybe two.

But hey, I'm more than happy we got this much.
