The Mutants - Episode 4

Just about the only thing that's interesting in this episode is the arrival of Professor Sondergaard, and that's only because the actor played Lobot, Lando Calrissian's assistant in "The Empire Strikes Back"... you know, the guy with the computer thing that wrapped around his head.  Yeah, that guy.  Otherwise, it's more poor acting and bad effects, especially the CSO where the Doctor and Sondergaard enter the radiation area to get that rock crystal thing.  Interesting also, now that I come to think of it (watched it a few hours ago, so forgive me) is the puzzling out of the message pieces from the Time Lords.  We also get a ridiculous cliffhanger as part of SkyBase is ripped open to space.  And does everyone get sucked (or blown) out into space?  No, of course not.  *sigh*
