The only stuff, that’s popular, that I have no opinion on is Babylon 5, mainly because I have not watched any of it

I highly recommend you watch it. Just keep in mind the first season (esp the first half) is tough, some bad dialog and acting. But it has important character and setting development.

The end of season 1 things get better, and by the first few episodes of season 2 you’ll be hooked.

At the end of the day, I bet you’ll acknowledge that B5 has BOTH some of the worst writing/acting you’ll see in a TV show, AND some of the best writing/acting you’ll ever see anywhere.
