Haven't read the entire thread, but my favorite "bad" Trek is TURNABOUT INTRUDER. I really should keep a copy of the house since Shatner's scenery-shredding in that thing always makes my laugh my head off.

Strangely, for years I "remembered" Shat being nominated for an Emmy for his "brilliant performance" in TURNABOUT INTRUDER. I was really disappointed a few years ago to learn it wasn't so. I thought that would have been so emblematic of the nuttier moments of that great decade... the Sixties.
