Wow, those DVDs will keep you busy for a while!
I love Star Trek: TNG, I think I've seen practically every episode (and more than once!) It's definitely one of the best Star Trek shows.
The first season is good, but probably my least favourite. When first I starting watching it in the 90s, I didn't see the episodes in order, so I'm more familiar with the show with its post season 1 changes.
Enjoy watching them!
