These grades are only my personal opinions, of course. These only include shows that I've watched in entirety, so far this year. Along the way, had to drop a few shows, gawd knows when I'm going to resume. Still have quite a few shows to start on, too.
Only grading the finales, not scoring the season itself. For example, overall, True Detective was really good (an A even) but the finale left me dissatisfied. OTOH, My Mad Fat Diary's season 2 was not as good but the ending was everything.
