    This is super helpful! Where is Season Three?

    • http://www.letswatchstartrek.com/ Lets Watch Star Trek

      We’re still making our way through the series. Sorry if we’re a little slow. We do an Original Series episode review every Monday (TNG Tuesday, DS9 Wednesday, Voyager Thursday, Enterprise Friday)

    Why does Spock’s Brain get a rating of 1 and then a recommendation to watch instead of skip?

    • LetsWatchStarTrek

      It’s bad enough to be entertaining

    • http://www.letswatchstartrek.com/ Lets Watch Star Trek

      It’s so bad that it’s entertaining

  • Irate Manatee

    Where’s “Turnabout Intruder”? I know it was horrible, but it should get a rating, right?

    • Malachi Ward

      We haven’t reviewed that one yet, but it’s right around the corner. We’re going through episode by episode, and we’re just about done with the third seasons of each series. check back soon!

  • Fernando Ferreira

    I’m just starting to watch Star Trek. Are the “skippable” ones unimportant to the storyline? Can I literally skip them eventhough it’s my first time watching the show? The ones marked as “watch” are either good or part of the – let’s say – “mythology” of the story?

  • J.J. The Great

    Where’s “The Cage”?
