I grew up with TNG, so having them on DVD is great and that's the bottom line. There are two downsides to this particular set, but they both have nothing to do with the episodes.
One: the packaging is horrible. The clear plastic is very thin and the top lid and side panels ripped off right away, but oh well, there's a grey, harder plastic box it's in, so that keeps it together, just not covered.
Two: The 3 sets of green plastic that the DVDs are in aren't labeled. The DVDs are labeled with season and the episodes they contain, though. Luckily, I have the book "Star Trek TNG: The Continuing Mission" that has a list of seasons and the episodes in each, with descriptions, so I can better find the episode I want. It's a great book, too. I'm sure you can look online, though, and find a listing of that info if you didn't want to buy the book.
Overall, a great series and DVDs are good quality. If the organization bothers you, you can just file them in a better container with labels.
