What is there to really say about Potemayo? I honestly don't see how anyone could connect hateful words to this series. Based on the attitude or feel of the show, I can't point out any factors that I necessarily disliked. It's more like I can only point out what was left to be desired. Then again, I never watched the specials, so maybe those could fill in the holes left in my heart when I finished watching the 12th episode. Potemayo is basically about a dude who wakes up to find an adorable yet odd creature in his refrigerator, and with this creature hedecides to continue living his everyday life. Comedy and Cuteness ensue.

This show isn't moving in any general direction, mind you. As in, there isn't really much of a story to base a discussion on. It's simply a slice of life. It's the definition of SOL, mixed with a little supernatural. (Potemayo and Guchuko could be considered supernatural beings.)
Though, despite this, the show is very enjoyable. It's kind of like comfort food but... it isn't bad for your health. If you're feeling down or just want to relax, Potemayo is a great show to sit back and relax to.
The best comparison I could give you when talking about the feel of the show would be Acchi Kocchi/Place to Place. These shows are EXTREMELY similar and if you enjoy one, you'll enjoy the other.

The music is simple, but its simplicity is what makes it so pleasant. It consists of strings(Violin/Cello/etc.), piano, acoustic guitar... and that's about it. They mix well with the visuals and together they create a comforting atmosphere.

I'm cutting this review short because as I've stated before, there isn't much to say about Potemayo. This is not a bad thing. The show is simple and straightforward. There isn't anything bad about the series, you just leave... wanting more. It doesn't feel finished and it's one of those shows where you wish it were longer. You want more content. You want to see more snuggling between Sunao and Potemayo.

All in all this show is adorable and funny and you should watch it.
And with that being said;
Honi. Honi. Honi.
