3D Kanojo: Real Girl is about this boy called Tsutsui and his relationship with his girlfriend. The story has a lot of conflicts that a normal slice of life would have, I think that the characters sometimes look real dead and their feelings aren't shown properly.
I wouldn't really recomend this anime for those who don't like slice of life, since every part of it is in this style.

For the first season, I must say that I am not impressed. I didn't expect a lot from this anime, mostly because there are so many others slice of life animes that follow this same format: An otaku boy that suddenly gets a girlfriend.

Even though the plot wasn't so interesting, it really got me to keep watching. I really liked characters like Itou and Ishino, they really don't look like most characters i know. Itou is this otaku little boy that wears cat ears, he really has some funny scenes. I'd say Ishino is the main comic relief of the show, I love her scenes.

The soundtrack has some cool songs, but it isn't really that soundtrack I'd place on my playlist to hear while I'm chilling or gaming.

The animation, I don't really think it has something so especial about it, there are some really strange scenes where the characters get really goofy and the lineart doesn't really make me satisfied. But I saw some promo images from the second season and I'm expecting more from the next season. I'd like a lot if the second season focus more in the relation between Itou and Ayado, since I think they're the best couple of the anime.

After all this anime is going to be a 5,5:

Plot: 1,5 (really not original, is a pattern that happens all the time and somehow people like me still like it);
Animation: 1 (it isn't that good but I've seen worse);
Characters: 1 (unoriginal, but i like Itou and Ishino);
Soundtrack: 1,5 (Has some cool songs);
Opening: 0,5 (meh, doesn't have such a great music neither a good animation);

Ok this was the first anime of the 405 I'm willing to watch. Yeah i know it seems ridiculous but I am really willing to complete this.

I really hope that the next season is good and show us things like a little bit more of Itou and Ayada's relationship.
