I haven’t watched the latest episode yet, but so far I’ve really enjoyed BoBF. My only issue is Boba as a character has been pretty forcefully pushed into being a semi-good guy.
If I were to ignore all the expanded universe stuff, I don’t think I’d see thus as too bug a departure from his appearance on Mandalorian. He’s a cruel deceiver in his initial appearance in the animated segment of the Holiday Special. In Empire he’s just another mercenary, the one who happens to succeed in capturing Han Solo and the others. In RotJ, he’s working for Jabba, though he seems distant and not loyal to him. In Attack of the Clones, he’s shown to be the son of a dangerous man. Jango, his father, while determined and ruthless, does not fit cleanly into being good or bad. In the Clone Wars series Boba appears as a vengeful and resourceful young man. Focused on his goals, and determined to fulfil them.
In BoBF, he’s revealed to have survived the Sarlacc he was thrown into, robbed and tortured afterwards. I Don’t think it’s too big of a stretch for his personality to swing in a lighter direction. He’s probably learned to appreciate life after being so filled with hate for so long.
