Grittier than your average Itou manga but still nothing to write home about if you checked and weren't shocked by his other horror mangas.
The first thing that may surprise you when checking out Mimi is the fact that for like the first time (at least this was for me), Itou starts the character not only in an urban apartment but the first scary monster is actually portrayed as deadly to the main character.
I'm talking Michael Myers or Freddie Krueger deadly here.
Those who haven't read Itou's other works may wonder what the big deal is when mentioning this tidbit but just so that I don't
downplay my own critical impression of Itou for those who like these type of horror manga - it's just a case that Itou relies more on village folklore than unstoppable monsters to shock his viewers and even here you will see a sharp decline in the series of short stories after the first one because Itou goes back to his bread and butter.
Other than that, the ending could have been great as it seems Itou tried to gamble with a bad ending but unfortunately at the last minute, he went back to creating open-ended good endings. Had he done so, this might have gone down as a manga better than his most well known work, Uzumaki. Especially the first creature. It is worth picking up just to see how the creature captured the Mary Sue protagonist but again, if you're not a fan of Itou, there's not much else to look forward to until the climax of the last story.
