I've started re-watching my TNG collection with season 1.
I'm really enjoying it and I know the show gets a lot better later on.
Q was great and the Farpoint Mission intro was a good pilot episode. The characters were really well thought-out.
The Ferengi were interesting from the get-go. They became more so on DS9, but TNG had a nice intro to their culture.
The holodeck was an ingenious addition to a Trek show that made 3 series capable of telling stories they never could have done without time travel or some other improbable mishap. I'm looking forward to future holodeck episodes as I watch on.
Lore was great. The legacy of Data is so much more interesting now that we've come full circle with even the Remans having access to B-4 (ST: Nemesis).
I'm waiting for Worf to start developing as I haven't gotten to "Heart of Glory" yet, but the Klingon stuff always gets interesting - as does the Romulan issues which come full circle through TNG, DS9, and the movies through Nemesis (the furthest in the future Trek has dared to go).
For many years I was sick of TNG (I did like the other shows better) but I have come full circle and am enjoying them now.
