Storyline

While beaming back aboard the Enterprise, a transporter malfunction results in two vastly different Captain Kirks being beamed aboard. His personality has in effect been split into two. One Captain Kirk is weak and indecisive, fearful of making any kind of decision; the other is a mean-spirited and violent man who likes to swill brandy and force himself on female crew members. Meanwhile, as Scotty struggles to repair the transporter, the landing party is stuck on the planet below with temperatures falling rapidly. Written by garykmcd

Clearly a stumble for the series
5 December 2006 | by (Bradenton, Florida) – See all my reviews

Of the early episodes, this is one that was poorer than average. This isn't to say that it was bad (no, that would be CHARLIE X), but it definitely was sub-par. Why? Well, it was the first episode where William Shatner was allowed to chew the scenes--with over-acting galore! Shatner plays dual roles--an evil id-like Captain and a wussy and indecisive Captain. It turns out that the real captain had himself divided into the two halves and the problem was to first identify that there were two Kirks (people just thought the real one had gone nuts) and then figure out how to re-integrate them. All the meanwhile, a crew is stuck on an icy and craptastic planet awaiting transportation back to the ship (note--they must have forgotten that they had the Galileo shuttle craft). A watchable but not especially memorable episode that features overacting--and then some.
