That was pretty excellent! The first episode was impressive mostly as a remarkably accurate visual recreation of TOS, but this one added a great story to the mix - one with actual themes and messages, no less! Even the acting and dialogue are way better here than in almost all other fan films. I would go so far as to say "Lolani" is better than many actual TOS episodes! (and certainly better than STID)
The only thing that still bothers me a bit is Dr. McKenna. It's not even that I don't like the character as written or the addition of another woman to the main cast, but the fact that the actress looks like an extra from a Star Trek porn parody is incredibly distracting to me. Maybe her push-up bra, awful wig, and pornstar make-up could be toned down a bit for the next installment?
Lou Ferrigno's voice and accent(?) were a little strange, too, but I got used to it after a while and thought he was actually quite good.
