I'm already drawing certain parallels in my head
G'kar reminds me of Garak
Sinclair reminds me of Sisko
Ivanova reminds me of Kira
Girabaldi reminds me of O'Brien
Londo reminds me of Quark
Dellen reminds me of Dax a little in that they are mild mannered by wise and dangerous.
I don't really see a Odo or Bashir equivalent, but the familiarity is what's getting me through a relatively weak first season. I'm now on an episode of importance according to
@BaldingSoHard where Sinclair is kidnapped and forced to revisit what really happened during the war. Good episode.
