Finally seen it. I wasn’t a huge fan of the first 3 seasons, they were OK but much worse than Clone Wars, but the 4th season was the best one. And the last bunch of episodes, absolutely beautiful.
I have a non-spoiler question - is the bearded guy in Return of the Jedi actually Rex?
I’d say it’s very heavily implied, but it’s not technically confirmed. So it’s really up to you to decide if it was or not.
