Star Trek TOS: Catspaw

If you can imagine the Star Trek crew doing a Halloween special then you would have this episode. It is hampered by budget restrictions, hell, you can VERY easily see the strings working the alien puppets at the end but with some imagination this Robert Bloch scripted number is an enjoyable bit of fare. Antoinette Bower joins the list of aliens trying to woo Captain Kirk and this one is also of note as it the episode where you can clearly see James Doohan is missing a finger.
