First giving the headlines of the review:
1. It is a deeper story than is usually perceived
2. It is not exactly a typical anime
3. There is little one wants to change about it
Now moving to jumbled subsections:
Story 9/10
Seemingly it is a non-existent story of just a boy staying with his strange cousin and getting along with her, meeting friends and seemingly the story stops midway. I look at it in a different light. The story is about a boy, who came to a city watched by aliens and finds every person strange and weird. The rest of the story takes him (and the viewer more deeply) into how different people, make things up, act certain ways, hide things deep inside, to show an outer covering that isn't what they are inside.
The story starts with him mocking the alien stuff and ends (till the 13th episode) in him questioning whether aliens do exist or not. And other than a few moments, it is all realistic. Now all this deep and slightly emotional (for some) story is well hidden behind cheeky, relatable, and funny characters that make the anime cute but in a warm way. It leaves you happy.
Thus it is basically a mix of a deep underlying story of psychology well woven with funny and quirky plus cute moments. It doesn't have any harem aspects (some may hint it) and is not a typical anime of a normal guy winning over girls through sheer love of justice and good will.
Above, I have also covered Enjoyment so I will skip that.
Characters 10/10
Now the characters are actually well defined. After watching it completely it is almost as if you can tell what they might be thinking at such a moment or how they would react in a situation. They don't act out of the way and feel like proper... characters.
Art/Sound 9.5/10
Personally, I found the art very smooth, the style that SHAFT production has really shone and the glossy sweet faces matched well with the theme. The background, colors, details, and especially the hair... was beautifully done.
Personally, I didn't find a flaw in this anime and enjoyed it above animes like Bleach, One Piece, Basilisk etc. I hope that this review helps you.
