The strong point of Hen is the surprise that the main character has when she falls in love with another girl. You get a sense for how her mind works and the stops and starts it goes through as her instincts act on their own, which is something that not every mangaka can capture successfully. It tells you that the mangaka knows a thing or two about the human brain and it makes you wonder how much personal exposure he might have to gay culture. I like that many of the panels are dedicated to simple changes in facial expression, or reactions to a strange commentfrom someone else. It's a nice touch and it makes this series feel more like an anime than a manga.

There are some low points: there's a lot of sex in this manga, too much for a 16 year old character like the protagonist, and the ending is rushed. Eventually, the side story between two males kind of takes over the romance between the two lead female characters.
