People are going to call me insane, but I think I liked OUAT more than HEA.
HEA is a much bigger spectacle, obviously, but that was actually the problem for me. The combination of constant fireworks with constant castle projections didn't work for me. I can't look at both at the same time, so it always felt like I was missing something.
It would be better if they were staggered. Look at the castle for these projections, and then boom here are a bunch of fireworks! Now back to the castle for the next projection scene, etc.
Or maybe it does do that -- I've only seen it twice and once was from the Contemporary roof -- but it sure didn't seem like it at the time.
