So I thought I had seen every episode of TNG dozens of times over. But about 6 or 7 years ago while binge watching some TNG, I actually discovered there were 3 episodes I hadn't seen, "Firstborn", "Suspicions" and "Rightful Heir". I have no idea how I hadn't seen those episodes but I was certain I had not. Especially "Suspicions". I am so familiar with every episode, and it was actually a little surreal watching these episodes because to me, it was "NEW" Trek! Also, I just recently watched "Sub Rosa", I had always ignored it because I knew the premise and knew it was pretty well hated. But I finally decided to give it a go. It was... interesting, but I didn't hate it.
