Is Frieren good for anime intro?

Im introducing my girlfriend to anime. Im fairly experienced. So far we watched Erased, spy family, and steins gate together. She liked erased, loved spy family, and did not like steins gate. I haven’t seen Frieren yet and was thinking of watching it with my girlfriend. I don’t want to watch anything that would horrify a normie with her lol. Is Frieren safe and good for an anime noob?
