I give a 4 to anime that were just barely good enough to finish. If the last episode is even sorta decent, it’s often a 6. I have given a 1 to an anime once, when it was not quite bad enough to drop after episode 1 and made a huge step down in episode 2. If I drop after 1 episode, it doesn’t even make it to my list.
That’s just unfair! Unsportsmanlike! Below the belt! Stand up and fight her like a man, you coward!
