I don't care if you think otherwise tbh. Normally if it's a show I enjoyed watching it'd be a 7-8 and if i thought it as one of my favourites i'd give it a 9-10, 10 being one's i think stand out against others and just well done, as well as personal favourites. 6 is watchable. Anything 5 and below was just a waste of time.
I will admit that I'm a very open minded/patient/tolerant person for the most part and it does influence how I rate my anime/manga. I don't think i've read enough good manga to differentiate really bad ones yet so i'll go over my scores for my manga eventually.
