I base mine on how much I enjoyed a show. I will give credit where due but in the end what is the point of watching a show that you're bored by. I use the whole scale in accordance with the MAL rating scheme. When I feel a show deserves a .5 I will round it down. I won't rate shows that I drop (even if I hate them) as I feel it's unfair to rate something that I haven't finished as opinions can change.
