Okay, I'm coming late to the party here, but I just saw it tonight and I can't resist weighing in. FWIW!...
I liked the effort overall. It was interesting to see an attempt to revisit such a familiar and classic story, and in many ways they did it well. Anson Mount was great, as usual. However, IMHO the episode suffered from three things:
First, the continuity just doesn't work. In TOS Pike had handed off command of the ENT and been promoted
before his accident, as evidenced in "Menagerie" by Kirk's surprise on learning of the accident. If Kirk had inherited the ship from him as a result of it, he obviously would have known. This might be handwaved away as a minor glitch except that the entire plot literally
hinges on Pike still being in command because of that change.
