"Machines just don't like me."  This was an interesting interpretation of this specific kind of tale.  Back in the day, a lot of people were computer-phobic largely because it represented another chapter in the mechanization that cost a lot of people their jobs.  With computers now so ubiquitous that I can't help but use one to aid my enjoyment of Mystery Theater, it seems a bit paranoid now.  However, this interesting twist in this episode is that it's not the computers themselves that are sentient and evil, it's that metal itself is alive and always has been!  Science fiction.
