It's a reboot of the original series that remade a sequel. That can be part of the reason people have had that reaction.
They dumped the history between, and had them meeting and serving together for barely a year.
Without the history and all the years spent between Kirk and Spock, Spock's reaction looked very generic.
Everything was rush, rush, spend a bigger budget, throw everything in, try to get bigger box office.
It has too much 'blockbuster' written into it. The Carol Marcus underwear scene was widely seen as unnecessary, except as another gimmick. Still hot though
