The timeslot was the biggest issue, I think–I was getting a little burnout from so much Once every week, and then nothing during the hiatus when I would have craved it.
I think that losing their hatter also hurt the concept somewhat. Wonderland shone its brightest when Cora took over for a bit–having just a bit more overlap with the things that make Once its best (and I admit the creators don’t always seem to know what that is) would have helped.
