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.
I'm not talking about the shows. I'm talking about the storytelling methods. The post implied that episodic TV is considered an inferior format, which doesn't make any sense since they decided to return to that format for Voyager.
