"Lolani", like all of Star Trek Continues thus far, emulates the look and feel of the original series with loving and quite frankly amazing fidelity. Just as importantly, this episode also continues the original series' exploration of morality and succeeds brilliantly.
There is little specific I can say without spoiling the experience, and that would be a disservice. Suffice to say that the entire STC regular cast was superb again, and the guest stars fit their roles to them like gloves. Fiona Vroom tore at my heart, and Lou Ferrigno delivers as an urbanely savage villain--not an easy character to portray, but he made it look easy!
Emotions run high in this episode, and the issues raised remain in your mind after it's over. That's the hallmark of a great presentation in any medium. Just watch it; you'll be happy you did.
