1. TNG - The show at its best; classic episode after classic episode. You can count the bad ones on one hand. 2. ENT - I really enjoyed the Xindi arc; the show was finally starting to come into its own. 3. DS9 - Its best days were still to come but this was a strong season with plenty of good showings. 4. TOS - Well, yeah. Lots of clunkers albeit the whole season had an interesting "feel." 5. VOY - I could barely get through it; for me almost every episode was so bland and stale. There were a few good ones - all at the tail-end of the season. Thankfully brighter days were ahead in seasons 4 and 5. I'll abstain from ranking Disco as I haven't finished season 3 yet.
