^I'd agree with that. I think the mysterious element that surrounds the Romulans makes for more compelling storytelling. The Klingons are interesting, but you can get a good idea of who and what they are watching one or two episodes of TNG. The Romulans are much more complex and require watching several episodes to get a sense of their history and culture, as well as their current standing in Alpha Quadrant politics. Information about them comes in small doses.
