There are things you just have to expect from a prequel, especially a prequel to something made so long ago. I don't blame a modern-day female character for not being written like she's going to naturally turn into a dowager from a 1960s show. Nor do I find fault with Uhura being so incredibly impressive right from the start as a cadet, given that she will eventually be relegated to answering Captain Kirk's phone calls.
Chapel feels like a departure. I don't blame them for not writing a character like she's going to naturally turn into a dowager, but I blame them a little for using an established character that they didn't need to when they didn't intend to be truthful about it.
I do think it's a mistake to expect characters who were on TOS to be identical to their portrayals there. Uhura being a fresh-faced cadet, still getting her bearings in Star Fleet should set the tone for what we look for. This is a full five year mission (or so) away from Kirk taking over and we don't really know how long Kirk was commanding before TOS.
Like, people change. Five years of To Boldly Go-ing can leave a mark. I'll be interested to see how they handle it, since they do appear to be interested in addressing how events affect the crew.
(On the third hand, it does sour things a bit that we know that T'Pring will end up being a manipulative shrew who engineers the death of a Starfleet captain because she feels unloved).
