Not watched much anime as of late, but I have dived into Emma and watched the first two volumes so far.
The first few episodes seemed to move a little slow for me-- while I instantly fell in love with the characters, animation and music, I sort of felt by about episode 4 that I was half-way to two-thirds the way through, but then it really started to pull me in, and as each episode goes by I feel I don't want it to end.
It definitely picked up the pace by the end of vol. 2, with Emma and William's relationship starting to ignite. It does make me think, however, what the next season will be like and how they can expand on the story after this season, but there's no point in speculating until I've finished the last two volumes. It all depends how it ends I guess.
