I loved DS9 (it's probably my 2nd ranked series behind TOS), but the downside is that it has no re-watch value for me. The "serialized storytelling" is just too hard to get back into. No matter how much I liked Lost or 24 or Game of Thrones (for example)...these shows with the complicated story arcs and multiple characters etc are too much time for me to go back and watch again. I've tried...lord knows I've tried...but I just don't have that kind of time.
I really enjoyed the whole story arc for the 11th Doctor but for whatever reason...I can't seem to be able to watch it again either.
