I avoided this one for a long time, but enjoyed it once I gave it a chance. Not knowing anything about Utena other than the most cursory of details, I can't comment on the changes to those characters and events, but the changes made to the Eva characters and events are handled nicely and the two universes appear to have been integrated sensibly. The script format in and of itself isn't a bother, but the way it's formatted is a little annoying.
