Perfect Sakamoto does everything right that he has absolutely no flaws. The only flaw of the anime is the fact that it doesn't have a plot, mainly revolves around Sakamoto the Greatest as he does things to overcome anything despite it might be occasionally funny and seemingly idiotic - but Sakamoto doesn't allow you to see those parts, because he's a bishounen! Anything a bishounen does is neither funny or idiotic.
Sakamoto is also a perfect character to the point he does not undergo any changes as well - surprise, you might think he would receive a power-up for being overpowered as a perfect character to further upgrade his OP status, but his only power-up is to be a massive chick magnet (and some males as well) that seems to level from normal, high school girls to aunts. All other characters are nothing compared to him as they revolve around Great Sakamoto for being the greatest.
Sakamoto makes the art of Sakamoto great, though I have nothing much to contribute when he has already contributed to it.
The overuse of one of the soundtrack for everything Sakamoto does will be attached to you in one way or another as they will use it every time Sakamoto does something great - pretty much all the time because Sakamoto is the greatest person every alive.
Overall "Haven't you heard? I'm Sakamoto" or known more as "Sakamoto desu ga?" is a decent comedic anime revolving Sakamoto the Greatest being overpowered and cool as well as great in capturing the hearts of older women for being too perfect of everything he does. The ending was applause-worthy for it features his departure, both his school and the anime world being the Sakamoto the Greatest and will remain in our minds for perhaps a new religion of Sakamoto.
It was rated slightly above average as I seem to lost my ability to laugh after 4 episodes in, and I have no idea why. The comedy probably is overused around Sakamoto the Greatest that it has lost its charming point of comedy, or perhaps the turning point of the story circling through the shady society of school turns Sakamoto the Greatest slightly grim yet he does not portray any of those in his perfect bishounen face. On the last episode, we finally know that Sakamoto the Greatest is in fact not some pan-face, heartless, emotionless bishounen who knows nothing but to portray his bishounen-ness and is capable of changing emotions makes Sakamoto the Greatest slightly relative to human and not some alien in human skin.
