I base my rating system on the 5 rating system. One means i didnt like it, two means it is ok, three means i like it, four means it is very good, 5 means favorite or Masterpiece. Then i convert the score to 100 based system. For example, If a show is a three, then i multiply it by 20. Then try to compare it to stuff above it and below it and do some changes if necessary. I will ask myself “do i like this show over that or not?” If i reach a point where i cant decide between three shows, i then stop there and leave the score as it is. I will only think about the show’s overall quality. I wont think very deeply on why or how that show is better than the other. I will just trust my guts. It might seems complicated, but i do this in seconds. TL;DR:
