The 15 or so minutes of this that were actually a Star Trek episode weren’t that great. The other 35 minutes devoted to Gene Roddenberry’s attempted spin-off were worse.
The episode starts badly: that incredibly difficult and dangerous time travel stuff? Yeah, let’s just boogie back to Earth for no clearly defined reason. By the time the ditzy secretary turns up the episode is well and truly off the rails.
Not a great finish to Season 2, but not the worst episode so far by any means.
55 down, 682 to go.
