The admiral was great; Michael and other characters crying/shouting almost constantly were not. They are supposed to be the best of the best, yet they behaved like whiny teenagers.
No excuse for Michael though, she really put me off.
To their credit they did joke about get behaviour in season 3.
On the other hand, I really loved Saru. Getting him replaced as captain... I don't know if I want to watch season 4 :/
