The idea of being invisible to all except for a certain someone (or her family, specifically the Kubo's) is enjoyable.
The art style is what defines this show. It was made intentionally cute the same as the art style on the manga. It was adapted beautifully.
The plot was predictable. On the first episode, you could say that Nagisa Kubo tells to herself "He's the one". Junta Shiraishi was decent, he's somewhat dense and predictable. Side characters are introduced pretty well, as they influence the story of the two main characters.
On the romance part, it feels lacking. It feels more like a friendship at start, but it definitely shows on the last. You can't change the source material, unfortunately.
Overall, the show is good. Have a cute art style, and good plot. The ending feels like it needs a season 2 though.
