Yaoi can be a bit tricky because like other forms of hentai, it's purpose is to arouse rather than to present the viewer with a complex plot and fascinating characters. This is actually one of the best yaoi I have ever had the pleasure of watching because it did a very good job at being subtle and sexy while avoiding the tired uke and seme stereotypes that typically bog down the experience and give the viewer almost a sensation of watching straight porn. Both of the men involved in this series are masculine, attractive, and aggressive in their own way, and their struggles with each other for power out and inside the bedroom add greatly to it's appeal.
A key point to this review for those who have not yet seen the series is that **this is a rape fantasy yaoi** with the rape presented in a more light hearted way. If you have experienced some sort of sexual assault in your past, you may want to pass this one up to avoid possible triggers. Moreso, if you don't find rape fantasy arousing or disagree with the concept, you will not like this show.
The art is very impressive compared to many other yaoi anime I have watched, in which the cover art is very good while the inside is lackluster. This is not the case with Koi Suru Boukun. What you see is what you get, and the art is consistently very nice through out the course of the show.
Not much can be said about the sound though. It's a porn, so having an elegant background score probably wasn't a huge priority for them.
If you want to compare this show to anime outside it's genre it probably wouldn't fare too well, but inside it's genre it shines. Koi Suru isn't exactly a unique yaoi, but it gets the job done in all of the right places and it should definitely be placed on the to watch list of every fan of the genre.
