I think that once you get beyond McCoy, Sulu, and Chekov, the nu-characters match their TOS and Prime film counterparts, and what people generally remember about the original characters, less and less.
nuKirk is greener than Kirk Prime was in TOS. In addition, especially in STXI but also in the first parts of STID, he's cockier. I don't know how many people on the BBS have taken his behavior in STXI during the Kobayashi Maru scenario and held it up as example of a violation of the Kirk Prime character. "Kirk Prime would never pew-pew with his finger while gleefully munching an apple," is the sort of thing they'd say, adding that, if he did, it wouldn't have been so blatant and over-the-top. Yes or no aside, the point is that the idea that the depiction of nuKirk is living up to expectations isn't fully supported.
Proceeding on to the other characters, the differences get sharper.
Next is Spock. We know that Spock Prime had emotional meltdowns on TOS, when he was under the influence of alien spores or undergoing pon farr. However, his melting down because of (at least what were arguably) external events, as he did in STXI at the destruction of Vulcan, was something that we'd never seen before. His emotionalism compromised his fitness for command, which is something else we don't remember from the series or the original films (I'm blocking STV, so maybe there's something there; I'm not sure). Arguments about whether this is how Spock Prime would have behaved in a similar situation aside, and arguments about whether it was just an unclever way of getting Kirk into command aside as well, nuSpock himself played against expectations in STXI, by having his emotional reactions matter so much to the story.
The two biggest exceptions to the notion of playing up to expectations are Scotty and Uhura.
In Scotty's case, he took an antagonistic stance against Kirk in STID, which elevated Scotty morally above Kirk and which materially advanced the story. While it's accurate to say that up to that point, Scotty was characterized to capitalize on expectations of his TOS depictions, particularly those in the TOS-Prime films, I think that the Scotty we saw in STID revealed and brought to the fore a side of Scotty that we rarely, if ever, saw before.
In Uhura's case, her relationship with Spock is quite obviously explicitly not what most people remember about her. Issues as to whether nuUhura is deep enough or independent enough are irrelevant to the actual point here.
This is not an evaluation of whether the characters were handled deeply enough. Pretty much by default, though, nuScotty and nuUhura are deeper than their Prime counterparts.
And whether Orci et al. were the best writers or not is really quite a separate issue also. The nufilms are not immune from numerous criticisms. However, the idea that the characters were only played to expectations isn't really what happened; that's not what's going on here. At the very least, there are significant beats that go against expectations.
