Not to be confused with favorite series. I think my favorite season is ENT sesson 4, which is funny because the series overall is def on the weaker end of the spectrum, and i dont think any particular episode of the fourth season is Star Treks very best, its just the season that has more good than bad episodes of any season of Trek I can remember. Next would be DS9 season 6 and TNG season 3 and so on. Whats your choice?
I'm currently watching Deep Space 9 for the first time and The Visitor is the best 45 minutes of television I've ever watched, so I guess DS9 season 4 even though I've only watched a few episodes from it at this point.
