I remember back in the day when TNG would be reran in daily syndication. Even before the DVDs came out and I was not an early adopter of those, every time they got to season 5 I got all depressed because it'd be months of snoozing before they got back to season 1 again. At least they didn't repeat episodes one per week.
Rewatching preferred episodes or a one-off for a long-forgotten adventure is preferable to doing a marathon, in order, per day or week... for me, anyway.
