On the first look this maybe just a typical harem anime which involves dense male main character, however Sakurasou Pet na Kanojo brings definition of harem to another level.
Story: 10/10 (Magnificent)
I put 10/10 for the story because it has a very deep meaning and morale for the watcher. Some of them simply realistic and makes me change my view about world and how I should face my problem. however there are still some miss-match if you looks it thoroughly, but you can ignore it. We are not researching like a scientist in laboratory right? Well o put bluntly, Sakurasou gives you a warm and heart full impression and more than just a male main character that chased by bunch of girls.
Art: 9/10
I can not say much about art, however the way they draw and animated it is so good and match for the genre
Sound: 9/10
The Opening and Ending for 1st and 2nd season is good and vibes off a enjoyable atmosphere
Character: 10/10
There are no background character in Sakurasou, you may think they are just typical classmate or something but they will undergo a development like other main character. And how the author describe every character is just too perfect and makes no character disposed in ravages of time.
Enjoyment: 10/10
Believe or not I already watch Sakurasou for 3-4 times already, there are some heartwarming scene and the story is just too fabulous. I find myself still enjoy it even though I have already know the plot. This is a fine example of good plot combined with good character
Overall: 10/10
This anime is beyond stereotype harem genre. Anyone who watch this should be prepared for amazing event and prepare a lot of snacks because maybe you will find yourself watch the entire 24 episodes in 1 day. Enjoy~
