Investing in them in epic??  They got rid of a show for a coaster because they knew better lol.  That was even before the park even opened.  And honestly, I feel shows like T2:3D work because they are more like attractions than open air show venues.  But again, a year round seuss show is begging for history to repeat itself especially if it isn't real tech heavy and mind blowing.  What they are doing for 2 months with the grinch show is just fine and what the patrons want.  I will give you this, if they can find a smaller venue for a story telling seuss style show, they may go over well for the little ones.  With some razzle dazzle here and there but I have lost faith in shows at universal personally.
