I remember when my parents got a VHS of the first Voyager episode for me from Blockbuster, before it aired here
It was amazing, I had a new Star Trek series in my hands; I watched it hanging on every little detail. I really loved it, despite what people may think of the first season. I thought the Kazon were interesting and the Delta Quadrant seemed like somewhere far from civilization with these tribes wandered around salvaging things like Mad Max. I remember the episode with the singularity, and thinking it had really cool believable fringe science, like something off BBC's Horizon.
I continued to get some Voyager and DS9 episodes from blockbuster before they aired on BBC. Voyager was, several years later, also the first Trek series that I ever got bored of, watching a VHS of a new episode; I think it was around season 6, when I fell asleep during a Trek episode for the first time ever.
My impression to this day is that the first five seasons of Voyager were good, and that Season 4 is one of the finest seasons of Star Trek in particular (Seven's character arc was damn good material; the Hirogen, Year of Hell, the Relay Network too), but that the actors and writing felt tired in the last two seasons, and the Borg were neutered.
ENT on the other hand... I can enjoy it for what it is, but it still feels like many bad choices were made.
