"Oreimo is an anime that you more of less can make up your mind about from the get-go. It’s a series that knows it’s audience and strives to be the best in can be for that particular viewership. Does it suffer for it? Sometimes, but only because it’s almost too clever for it’s own good at times. This isn’t for everyone, but can be enjoyed by almost anyone. While being a relatively simple affair, Oreimo makes for an incredibly nuanced and intelligent comedy anime that has a strong sense of identity and purpose, a rare gem indeed."
