I'm not thrilled with having M'Benga and Chapel serving on the Enterprise this early, nor with making that one character a Noonien-Singh.
I do like having an Andorian or Aenar aboard ship, however.
I'm nearly the same, except I'm disappointed that it's Uhura, Chapel, and a Noonien-Singh. I'm sorta OK with M'Benga as I'd like to see his character fleshed out. However, overall, I agree none of these were necessary. We have enough evidence that it's possible to make a very successful Star Trek show without incorporating TOS characters on a regular basis.
Dang, Uhura spends her entire Starfleet career on the Enterprise it seems.
