I liked the set, myself. It had the 3 big elements in it (Hollywood sign, movie screen, marquee) but none of those alone could really be a great unique entrance set (we've seen the Hollywood sign-style thing at No Way Out and the big screen at SSeries 2002). Plus, I liked how the ramp was configured as a five-pointed star and there was a red carpet to the ring. Had they not used the the night before, I would have had those giant Slammy replicas in there somewhere as well.
Also, I do believe that JBL and HHH may each have had the greatest entrance in the history of WrestleMania.
