The flashbacks should be presented straight in chronological order and a little bit faster, then episode 4 should be the first episode. Other than getting out of the sarlacc and the tusken stuff, absolutely nothing happens in episodes 1-3. Episode 4 actually gives Boba a motivation, shows a meeting with the crime bosses, and gives an antagonist. The episode seems to understand this about itself because it even introduces the wookiee like he’s a brand new character we’ve never seen before.
