Well, Rinne no Lagrange was pretty bad tbh. It's pretty much just strike witches all over again but minus the fan service (at least not to the magnitude that was in strike witches). But I have a personally policy of finishing what ever anime I watch regardless how bad it is lol
Utawarerumono: Itsuwari no Kamen on the other hand was pretty good, but some people might get confused watching it if they've never played the VN or watch the original prequel version that came out over a decade ago.
