As much as Rem stole the show in the second half, the scene with Emilia at the end was just fantastic. A satisfactory conclusion to the current arc too. I am assuming there is more story to tell if they want to and I'd certainly like to see more of this world and how the competition to determine the ruler progresses. There are still a lot of mysteries to explore.
Overall though, a great series. One which I couldn't wait for the next episode of each week. If I have one criticism it is that the characters would sometimes monologue for a bit too long and sometimes the "suffering porn" for Subaru seemed to be heaped on through a bit of contrivance, but despite all that it was an engaging and fun series that managed to take what is by this point quite a tired premise and inject new life into it.
