What I don't understand (among many things) about this whole slew of criticism about Burnham is the notion that there was no character development in her at all and she's the exact same as she was in The Vulcan Hello. Hasn't she become much more in touch with her emotions and much more at peace with who she is? Why should character development necessarily mean learning to play by the rules, becoming a team player and unquestioningly obeying authority? Character development doesn't equal becoming a model officer, and this line of thinking isn't unique to Burnham, as Tilly is often criticized as well for not showing any signs of developing into a cool-headed, by-the-book walking Starfleet recruitment poster. Is it really impossible for people in the military to develop in ways that make the constraints of uniformed service a hindrance to them realizing their full potential?
We wouldn't have seen her having serious difficulties readjusting to the rigidity of rules and the chain of command after a year of freedom if it wasn't significant for her personal story arc. She only accepted becoming Saru's XO at his insistence because she doesn't see herself as XO material anymore. She has taken on a personal quest that is bordering on obsession and is already negatively affecting her ability to fulfill her duties as a Starfleet officer. Call me naive, but this doesn't seem like some "Burnham disobeys orders because they're dumb and gets anointed as the second coming by the Admiralty because of it" plot. She is obviously conflicted about her place and role, and is probably going to experience even more friction between her Starfleet duties and her crusading, responsibility-hoarder personality. Nowhere is it written in stone that she will be proven right about everything and Starfleet will just fall in place behind her and make the Burn their mission because she made a teary speech.
