is easily my favorite followed by seasons one and two of The Next Generation
and season four of Enterprise
If the rest of the series/seasons fell into a black hole, I wouldn't miss them.
DS9 hands down on all of them.
Best good story to crap story ratio.
I found that Deep Space Nine
had the most episodes that were simply unwatchable, more than Voyager
. It had some masterpieces but they were buried underneath far too many rubbish episodes.
