Very sad to hear this. When DS9 first started, I initially found it difficult to get into, although I'm not sure why. I found the name "Cisco" a bit weird, as I remembered kids going on and on about "Hey Cisco! Hey Pancho" ie "The Cisco Kid", maybe in the very late 60s. But I didn't even see it, because we didn't have a TV then.
It was the interactions between Odo and Quark which I started to enjoy. I also remember an episode where Odo had to (was it "dissociate"?) pour himself into, I think it was Deanna Troi's (the doc/counsellor) overbearing mother's handbag(?)
I recently started watching DS9 again... and I've never seen the final season at all!
