DS9 is both familiar and different enough that it'll be interesting to see what you think of it.I've bought the complete DS9 boxset on "Cyber Monday" and plan to finally watch this series over the holidays.
When growing up, I watched a lot of Star Trek ("Raumschiff Enterprise" in Germany), mostly TNG and VOY. I more or less completely skipped over DS9. The few episodes I catched here and there seemed so utterly boring to me that I never tried to watch it seriously.
Then, after reading sooo much on the internet how it's many peoples' favorite and has this cool Dominion war arc AND having a friend who was always praising it for years... well, here I am, ready to repent and going in with an open mind.
I'm excited.
In some respects, it's the "Discovery" of the franchise before Discovery came out. Although the DS9 writers had the opportunity to establish this set of characters as diplomats and scientists before turning them into warriors Qapla'ing all over the place.
