I think I'd rather see a shorter (perhaps 4-5) season show with 10-12 episodes per season at one hour ala the "Game of Thrones" format with higher production values and fewer bottle episodes. Though I suppose that would necessitate moving away from regular cable television and towards "premium channels".
No, in fact, lots of regular-cable shows today have short seasons. Shows on Syfy typically either have 13-episode seasons or 20-episode seasons split in half and aired across two years. USA's dramas usually have seasons of 16 or 18 episodes that are broken into halves, generally with each half-season forming its own arc (though with both halves airing within the same 12-month span).
