I loved that they gave Dr. M'Benga some screentime front and center and showed that he can throw down if necessary, even if it was with the help of some super serum stuff.
And while I even loved his (and Nurse Chapel's ) elaborate fight scene and enjoyed the way they filmed it, I'm also not sure if it quite fits with Star Trek. Just not sure yet with the excessive slow motion. The camera angles however were some great artistic choice.
But overall one great start to season 2.
