You will have to disregard the fact that Kirk and a handful of intimates manage to pilot the Enterprise on their own. But this episode is written and performed with muscular vigour and attack, and there are some nice moments.

This "Star Trek," the liveliest and most likable of the three, will satisfy hard-core Trekkies and win more than a few new recruits to their ranks.

"Star Trek III" has a genuine spirituality, and, at its end, you may be surprised, especially if you're not really a Trekkie, to realize how moved you've been.

The central villain of the film is under baked though delightfully portrayed by Christopher Lloyd.
