Recognised by whom to be an "inferior" approach? I love arc storytelling, but you can't just throw shit out like that.
Well by most critics for one. "Deep Space Nine" is still a much better received show than "Voyager" in the popular media.
Just off the top of the head, DS9 features in both IGN's top 50 sci-fi shows list (#12) and Empire Magazine's top 50 tv shows ever list (#47) while Voyager doesn't. Over the years, I've seen DS9 praised much more than VOY and VOY derided much more than DS9 in various magazines and publications.
