This episode is very similar to the movies The Thing from Another World
the 1982 movie The Thing and also the book Who Goes There in it's plotline. That being the plot of who might be the monster in disguise, and nobody trusts anyone at all and resorting to accusations and violence. I enjoyed this particular episode very much and have watched it twice now. It also stars many familiar actors It also stars Burt Metcalfe before he got to be the top man behind the MASH series. This episode is worth a watch and and better than a lot of episodes which were really duds. The moral at the end is worth the price of admission.
