One More Thing...
One thing I forgot to comment on (I'm still talking about Children of Eden here): the amazing visuals that filled the screen onstage.
Someone put a heck of a lot of work into that, tracking down some great artwork, using visual effects to give it a striking (but never distracting) look, and managing to present it in a way that matched up to the music - an incredibly difficult thing to do in live theatre! I really liked the touch at the end, where they included shots of the cast rehearsing the show!
A special tip o' the hat to the responsible parties!
