This version of Boba Fett talks too much and takes his mask off a lot.
Mando is the prototypical lone gunslinger in a spaghetti western plotline, with his mask replacing Clint Eastwood's stoicism (to be fair, Clint Eastwood really doesn't have that many facial expressions).
Meanwhile, Daimyo Fett seems to be Charles Bronson with a heart of gold, except he isn't the underdog in this one as he has a posse. Not very compelling, to be honest. I hope the last half of the series is much better.
