One way to explore their culture is to have a subject character who can guide us into their culture and society. Spock represented Vulcanians and we learned their culture through him, and in TNG, Worf was that vessel to open the door to the Klingons --which wasn't interesting to me at all. DS9 had an opportunity to explore Romulan culture by having T'Rul as a recurring character.If you play Star trek Online you know that the romulans are really well done in that game and a very interesting multi faceted species.
On screen they are 99% of the time just devious and manipulative with little redeeming features other than they "occasionally" will surprise by doing the right thing.
Anyway, TNG and DS9 changes the klingons from being fairly one dimensional, I'd love to see the romulan get a fair treatment.
Since their home world was destroyed in the prime universe, it'd be a perfect time to show them rebuilding their society and maybe even building better relationships with the other major powers.
Is their an idea of what to explore with the Romulans? Does anyone have an idea of what and where to explore Romulans?
