What is an anime where you genuinely don't understand why it is as popular as it is?

For example, while I personally might dislike SAO, I can totally see why it's as popular as it is. It has a pretty cool premise, great animation and music, a harem element that probably resonates well with the target audience etc.

But what's an anime that is decently popular, but you just can't figure out why it's as popular as it is?

Edit: Guys, if you're gonna ad "I can see why it's popular, but..." just don't post lol. This isn't supposed to be about what you personally dislike.

Definitely, but they're the statistically significant audience by a long shot.
