1)Oreimo talks a lot about the anime culture of Japan. Comiket held in Akihibara, doujinshis, eroges that people buy. Yes, people have such hobbies and the society reacts in a disgusting way towards people who tend to have such hobbies.
2) Despite many people criticizing the second season because it focuses more on the relationships with different girls (harem) of Kyousuke rather than the otaku culture. I found Manami's arc to be quite good. An arc like that is rare in harems. I liked the humourous parts too.
3)Kirino's character is relate able, especially for those who have to hide their hobbies because of the fear that they will be seen in a negative way or simply because of the fact that people around them aren't aware.
Weaknesses:-
1)You can't help but notice that this anime for lolicons(fanservice). Although, I read the LN, cute girls wearing frilly costumes for modelling. And, the consistent use of 'onii-chan' in the LN is irritating.
2) The ending was very vague. I had problems understanding that one. Although, I read the explanations. You could say the author chose this ending because he wanted to avoid a happy end (unrealistic) or bad end(heart-breaking). So, not exactly disappointed but not happy either.
3)Kirino's character is annoying. No matter what the reason, her behavior gets on our nerves. Not to mention, she isn't even close to an understanding little sister even though she is living with her brother for a long time.
Should you read Oreimo? No, do not waste your time.
Not for those who have just started reading manga or anime though. It has references to other anime and for those who have been an otaku for quite a few years now, will know the references
This my first anime review, so sorry if isn't that good.
