the only good scale is
the Savage Critic scale. Take the 1-10 and condense them to 7.
Excellent, which is basically 9 or 10/10. The top of the top. Daredevil: Born Again, the fourth volume of Scott Pilgrim, Hawkeye #3 with the car chase, the Uncanny X-Men two-parter with Wolverine in Japan. Very rare. Exceptional comics that are, by defintion, the exception to most of the junk that passes for entertainment.
Very Good, which is basically 8/10. Strong comics with several notable areas of craft or achievement, just not enough to get into the top tier. Ya average issue of BPRD or Stray Bullets, that Spider-Man/Punisher team-up by Zeb Wells and Paolo "God" Rivera, The Private Eye by BKV and Marcos Martin. I wish every comic was this good.
Good, which is basically 7/10. Good comics! Likable, attractive, compelling, and/or highly comptent in their construction without being great in any real way. These are comics you will happily read, and next month's too, just maybe not something you re-read any time soon. Average issue of Saga, BKV/Stuart Immonen on Ultimate X-Men, Greg Pak/Aaron Kuder on Action Comics.
Okay is 6/10. Passable comics. Comics with just enough value that you didnt regret your purchase. This is where the vast majority of entertainment sits, including most comics. And if not here, then...
Eh, which is 5/10. This is the big shrug. The who gives a shit. The I couldnt even be bothered to finish this. I have no interest in reading any more of this series. This is not for me. No. *insert literally so many comics it makes you question why you got into this hobby in the first place*
Awful which is the 3/10 or 4/10 slot. Bad comics. Actively terrible art, trite dialog, stupid ass characterizations or story structure. Comics you seriously dislike cuz they are not good. Not even gonna name any, you just read some Awful comics Im sure
Crap, which is 1/10 or 2/10. I mean, this should be as rare as Excellent, or at the very least you're smart enough not to buy them cuz you see Crap a mile away. These are the bottom of the barrel. The real pieces of shit that make you question why comics exist if shit like this is published. Bad in so many ways.
