I went on this journey with my son during COVID.

Watch a handful of classic trek to get the idea. Balance of Terror, city on the Edge of Forever, maybe Mirror Mirror or Trouble with Tribbles. They will seem very cliched.

Start TNG in the third season and just focus on the best episodes, the ones that are 8s or 9s on IMDB. Be sure to see The Best of Both Worlds I and I, the original season finale climax.

Skip a lot of the first season of DS9. Low IMDb will tell you which ones. But watch almost all of the later seasons.

Then play Star Trek Attack Wing!
