I watched these this afternoon after I got home, and I felt they were a mix...
I like the concept of Boba not being a jerk naturally, but I think they are pushing that a little too far now as well... I can see him not offing the Clones and Killian because Killian showed a little kindness, but part of me also thinks he maybe would resent the Clones and should've been a little more sympathetic to Killian and not the Troopers I guess.
I also liked the whole first episode, I thought it was unique... I easily got past Bossk speaking and just assume that he is grunting and it's just him speaking English to be simplistic. I can accept that better than him speaking English really since I always felt he couldn't in ESB.
I felt the ending was like a lot of you have said... Kind of abrupt, and I didn't really see a need for Mace to capture him and act like a prick on top of it, and then for him to be captured at all... Why bother with that? Have him maybe cause some serious damage and escape. Voila, he wins... sort of. Mace was a real dick at the end too, which to me flew in the face of a true Jedi as well... I mean, you did decapitate his father. You could at least try to reason with the child on some level.
I loved Hondo's part, and that he's not a bad guy really, and that Sing's bad news for anyone who gets involved with her.
I cannot stand the thought that they're destroying Slave-I... on Jango's helmet, I think it is possible Jango had a number of helmets, like Jetpacks and possibly armor and other things. I can look past the helmet. Ships though... Slave-I isn't the only Firespray ship, but his is/was the only original designed one IIRC, which was sturdier, faster, more firepower, and that later models needed heavy upgrading to be anywhere near what Slave-I was. If they destroyed it, that really does poop all over the backstory for Jango/Boba a bit. I'm hoping maybe Hondo salvages it for Boba. I could see them having some future interactions, and Hondo nurturing Boba's sense of honor he got from his father.
I thought the last episode started out ok, but fizzled a bit once they got to Hondo's place. I liked the Underworld bits of Coruscant though, and whatnot.
I'm ready for next season to get here... Gonna be a long Summer without new episodes.
