Amok Time (TOS).
MeTV really took a hatchet to this one. The whole scene where Chapel tells Spock that Kirk has made the final decision to take him to Vulcan was removed.
Ditto to that. They also cut Spock's "my blood is flame" bit.
The only good thing was the movie that followed. "This Island Earth". I've never seen it before, but had heard about it.
