Like any TV show there were good and bad episodes in Star Trek TNG. Then again, I can't name any episodes that made an impression on me. Except "Encounter at Farpoint" because it was the show's first episode.
Same with Dr. Who: most episodes are forgettable, but some like "Blink" and "Silence in the Library" stick with you forever.
I'm lamenting the fact seeing more and more actors I grew up with pass away. Walter Koenig recently and most of the Star Trek TOS cast. Except Shatner, who'll outlive most of us.
R.I.P. Patrick Stewart: Captain Picard, Gurney Halleck, Professor Xavier and more.
