I didn't think this needed a season 3 but since there is nothing I can do about it. I'm on board and hyped to see the characters return. Hopefully KallenxLelouch becomes a thing.
I like Rem and Subaru, I think. I'm a little on the fence with Emilia. I want to like her, but she comes across a bit bland to me. I hope the second season, assuming there will be one, will change that impression.
One thing that really stood out to me with Re:Zero is that Subaru has a much more realistic portrayal than mc's usually seen in these types of stories, which are generally flat as a sheet of paper and less interesting than watching paint dry ( yes I'm looking at you SAO). His reactions to his situation make sense, and he experiences clear character growth. Which, honestly, was a lot more than I'd hoped to expect going in.
From what I've read, Emilia was kind of pushed in the back compared to the LN and will become the focus later on. I have no idea if this is true though as I don't read the LN. I'm just gonna hope there is a season 2.
