The Three "Yusaku" tenants I follow regarding anime:
1. Nitpicking and hard critiquing is no necessity unless necessary...enjoyment and satisfaction matter a lot, if not the most.
2. Character likability and/or development is a top priority for most cases; everything else comes second.
3. Trust your gut instinct and be reasonable, even while people around you aren't. Regarding of whatever flaws were presented in a show or not, what matters more is: Did you enjoy it enough? Did you feel enough satisfaction? Was it easy or hard to watch? Your resulting rating for a show should reflect that as well.
KEEP IN MIND that it doesn't mean I give generous scores that easily and that often. There are series I still enjoy a lot but still rate very low due to flaws I can't ignore or aspects I highly dislike.
My Favorites in terms of anime need all of these qualifications:
1. At least have a score of 9 or 10 by me.
2. Attained at least above average in terms of enjoyment levels.
3. Have at least one or two prominent characters I really like or love.
