If you want to (re)watch The Mandalorian leading up to The Mandalorian & Grogu movie release, start watching half a season per week (including The Book for Boba Fett, which is basically The Mandalorian Season 2½)!
If you want to chat with fellow nerds about it, I have a little Discord server:

For the next couple of months, we’re just planning to do informal/async watchathon following that schedule.
