In the casting, there was a clear intent to differentiate the show from its predecessors. Genre stalwarts Tony Todd and James Earl Jones were considered for Commander Sisko before Avery Brooks. The one letdown at the time was that Michelle Forbes did not carry Ensign Ro across from The Next Generation, but when the explosive Nana Visitor defiantly slapped her hand on a console in the pilot episode, viewers knew they were in for a different crew dynamic. In fact, the two-part pilot show ("The Emissary") is largely responsible for DS9's early success. Mysterious, spiritual, claustrophobic, funny, and feisty, it remains the most attention-grabbing series opener (apart from the original series') the franchise has had. The first year may have relied on a few too many familiar faces--like Picard, Q, and Lwaxana Troi--but these were more than outweighed by refreshingly detailed explorations of cultures old and new (Trill, Bajoran, Cardassian, Ferengi). As it turned out, Deep Space Nine was the boldest venture into Roddenberry's galaxy that had been (or ever would be) seen.
