I love Star Trek: TNG. I think a lot of people criticise it because it's very goody-goody. There aren't any particularly flawed characters, and only on rare occassions does it get dark. Usually I dislike that, but I love it in TNG. It's got this wholly positive view of the future and humanity. Even the darker episodes (like 'The Lower Decks') are hopeful.

It's got great characters as well. Data's character progression throughout the series is a joy. Picard gradually moves away from all-out diplomacy, particularly after his encounter with the Borg. La Forge is the nicest guy ever, and so enthusiastic.

I just get absorbed in it.
