At first I wanted to use the headline "Jarring Tonal Shifts: The Series", but that would have suggested I disliked it, which I didn't.

Really liked it, and really enjoyed the time travel aspect, with caveats about the ending. It's just that you go into it expecting a fluffy comedy with love and time travel, and, especially in the second half, are constantly being ambushed with servant/slaves being beaten to death for trying to be cured.

Also, the ending makes no sense - yes it fulfils the expectation of happily ever after, but it's a huge plothole.
