(Average+) If It's for My Daughter, I'd Even Defeat a Demon Lord

Series in one sentence:
Little devil girl who looks nothing like a devil turns every adult man into a sappy fool.

Series in more sentences:
A young and talented adventurer finds a little girl during one of his travels and learns she's an exiled devil, more importantly, her father has died and she's alone. The girl's situation and trauma plays on his heart strings and he decides to take her in himself. 

Everything she does excites him and he becomes addicted to her love, while she does everything she can think of to please him.

For starters, I didn't think the girl was all that cute. She was very "moany". Maybe Japan finds that kind of voice acting cute, but it never ceases to annoy me. Not every facial expression needs to be accompanied with a sound, you know. But I got the point; the girl is smoll and innocent and all that.
To see the guy go absolutely berserk over how cute she was was funny, but it would've been funnier if I knew what kind of person he used to be before that period. I can't even tell you if he has a personality, besides being in love with his new daughter.

As for the story itself, it was basic. The first few episodes were great; here the girl was young and only spoke a few words, but the moment she could speak and went to school, things became pretty boring.
Here we have a mysterious child, described to be a devil, with a backstory attached to her and her race, and the anime explores none of it. It only teases you by sharing a sentence's worth of info now and then. 

Only sometimes a real conflict happens, like people trying to kidnap her for money, but every other time we get plot elements like a female friend getting pregnant, a stupid whiny wolf baby who won't stop screaming when she doesn't get her way, or the girl showing worry she won't get to be with her foster father when an adult.. riveting.
One episode had these extremely lengthy scenes that showed these two doing absolutely fucking nothing. It hurt my soul, like the creators didn't know or care how to progress the story that day.

I guess it's not a waste of time, you can watch this and be entertained, I'm just a bit disappointed the show didn't "do" anything truly exciting.
