This is my first time writing a review, so it may not be well written or helpful, but please bear with me.
First off, I want to say that if you're looking for a very serious romantic anime like Clannad, keep on looking, because this anime would not be for you. But if you're looking for a good laugh and something to pass the time, then look no further.
Story - 6
Just your usual "Alien comes to Earth" anime. Nothing that stands out, nothing really unique. But this anime isn't really centered on the story. At least to me. The one major
flaw of this anime was the absence of an actual conflict/goal. *Minor Spoiler Alert!* Every time that some alien was trying to kidnap Mahiro or destroy the Earth, it was always for some really stupid reason, which was funny in the beginning. I expected the crisis at the end to have a little more depth because they had a pretty decent plot. They could have done so much more with it. But instead it followed the usual pattern, which was a big disappointment.
Art - 8
Beautiful art work. I loved how all of the characters looked, and everything was visual appealing to me.
Sound - 7
The opening and ending. Although they fit the anime well, I didn't really enjoy them that much either. I thought that the background music fit each of the situations fairly well.
Character - 6
Not that much to say here. Nobody really stood out for me except Kurei, Tamao. I think that they could have done a lot more with her, since she liked Mahiro, but also gave advice on how to make Mahiro fall for Nyaruko.
Enjoyment - 8
I really enjoyed this anime a lot. It always kept me entertained with their constant flow of gags, but sometimes they can get a little old and annoying.
Overall - 7
This is a pretty enjoyable anime overall. This is not a series that you really need to watch, but I think it is worth looking over.
