I use a five point scale to rate anime. I rate, summarily speaking, based on how much I enjoyed the anime. Parts which are important are execution, ideas, and impact on me. I obviously have personal tastes, and will like certain things and dislike certain other things. Other than the lowest end of my scale, I think I enjoyed all anime I list. Having no number for 'Days' means I don't remember the date I started watching the anime and/or the date I finished watching the anime.
