8 is definitely too short unless it’s a one season mini series. 13 is probably just right. Anything longer seems like it’s going to be full of filler material to stretch things out. Remember that older shows with 20 episodes often had one or two clip show/flashback episodes to meet their longer season order.
In the past couple of years I’ve seen a few cases where 8-episode seasons contain a lot of filler, maybe because the writers felt like they couldn’t bring in more than one major plot point in so few installments.
