To celebrate the 2010 Comic-Con, we present to you Comics & Graphic Novels vs. the Critics, an exhaustive countdown that includes movies based on everything from superheroes to graphic novels, from manga to strips from the funny pages ? in order of critical approval.

We can see those thought bubbles above your heads ? you?re wondering how we compiled this thing. Here?s the breakdown: every movie here originates from a comic book source of some kind, not another medium (we know about the Alien vs. Predator graphic novels, but the movies aren?t based on the comics). Only movies with 20 or more reviews are included (sorry, Fritz the Cat), and we use a weighted formula that takes release year and number of reviews into account (see How It Works for more). We also omitted all TV or straight-to-DVD flicks.

Now remove the protective plastic bag, flip to the first page, and dig into Comics & Graphic Novels vs. the Critics!

• Each critic from our discrete list gets one vote, all weighted equally.
• Reviews without ratings are not counted toward the results.
• Because reviews are continually added, manually and otherwise, we have a cutoff date at which new reviews are not counted. The current cut off date is 7/20/2010.
• We use a weighted formula to account for variation in the number of reviews per movie per year. The winners are determined by the rankings,
  designated as the "adjusted score," after applying said formula:

  t + ((r-a) ÷ a) if number of reviews > average number of reviews for
  corresponding year.
  t * (r ÷ a) if number of reviews < average number of reviews for
  corresponding year
  t if number of reviews = average number of reviews for
  corresponding year
  with "r" representing the number of rated reviews, "t" the
  Tomatometer score, and "a" the average number of reviews
  per movie for corresponding year
