Edit: Oh, if Abrams Trek counts, then everybody in Abrams Trek not Kirk, Spock or Uhura. Worst casting ever. Other than those three the cast were treated as throwaway characters.
Wait, do you have a problem with the casting or the treatment of the characters? Very different things. I'd agree that there's not enough screen time for McCoy/Sulu/Chekov, but the casting is pretty awesome. and certainly by Into Darkness, Scotty is not treated as a throwaway.
