the guy from screen crush (ryan arey i think?) theorized that boba is different in this series because he's actively trying to move away from his father's legacy. the sarlacc and tuskans helped him come to the understanding that while he always thought it was his job to continue jango's legacy, that will always only lead to death. similarly to following in your father's footsteps not because you want to, but because that's what is expected of you. boba is now understanding that he needs to create his own legacy.
the interesting part about that, is that we the audience recognize boba as his own character because he was introduced first. jango was a bounty hunter because boba was, though that's backwards chronologically. i think this is causing such disconnect with the audience because the writers and the audience are approaching boba from 2 completely opposite places. this is just one of the many problems with having such a huge part of the star wars lore being from prequals. most of the canon on boba fett is a retcon.
edit: for what it's worth, i'm not hating the show... i just think that for anyone who's been a fan of boba this show is kind of requiring them to think differently about the character and lore and asking anyone to change how they think is always a tall order.
