Franken Fran is a well made paranormal dark sitcom. The manga is about a schoolgirl Fran, who has stitches on her body and resembles to Frankenstein monster, a human being brought to life by a crazy scientist. Fran was also created by a scientist and she spends most of the time operating and researching in his lab. She needs funds to keep the lab working, so she helps various people to make changes on their body for a price. That is basic start of a chapter - someone offers her money to make change on their body, she experiments and the outcome isn't as expected.

Sitcoms have overall problem of having no main plot, they rely on numerous stories which make characters react. This manga doesn't have feeling of progress, it shows only the situations Fran deals with, but it's only a minor negative point. Most of the stories are creative, quirky and well made, dark humor is very well placed. Some stories have more paranormal approach and more pages are spent on (pseudo)scientific approach to explain some things, but even those parts are decent at worst. Many stories are simple, but they are effective and don't contain anything unnecessary. I would say Sentinel parts are one of the most enjoyable,
Art is very good, anatomy parts and gore are very detailed.
Characters are mostly fixed and have a couple of traits. They react according to their traits and we learn patterns of protagonists, but new characters always bring quirkiness and unexpected situations. Fran is more developed character, she genuinely cares about nice people and has weakness to people with love problems, she also behaves according to her morals - helping nice people while punishing the ones she finds bad. Even though other characters from the lab appear through most of the manga, they rarely get the spotlight, such as Okita, Veronica and Adorea.

The manga is very entertaining and contains a lot of material to crack you up. The stories are well written, characters put in awkward situations, comedy on spot. Even though the character development and main plot are lacking, it's not a drawback. I see that more people relate the manga with horror, but I'd say it's more comedy. The manga differs from most of mangas and it's definitely worth of your time, if you don't mind gory moments.
