There are 3 episodes I remember being good - Enterprise Incident, Spectre of the Gun and All Our Yesterdays. And there’s a lot of crap, like the hippie episode, Spock’s brain and the last episode. Most of the episode are IMHO just forgettable.
I actually like The Way To Eden. It’s goofy and dumb, but enjoyable. And The Savage Curtain has a special charm.
