United Artists' vast, fifteen-house multiplex on the teeming 16th Street Mall may not be the most pleasing edifice, architecturally speaking, but when the lights go down and the credits come up, moviegoers can revel in every postmodern comfort: sculpted, well-cushioned seats arranged in the steeply canted, viewer-friendly "stadium" style, convenient cup-holders, and top-of-the-line projection and sound. Certainly, many suburban theaters boast similar high-tech facilities, but the Denver Pavilions 15 is downtown, and that's the greatest comfort of all for filmgoers who love city life.
