I guess at this stage it just isn't that important to me either way if it's an IP - moreso the execution. I've pretty much loved all the Universal Classic Monster houses, the All Night Die-Ins and Silver Screams, Alice Cooper (of course) - heck, I even enjoyed Saw. OTOH, I really didn't like some of our other IP houses last year, and I can think of several other IP's over the years that really didn't float my boat. And then I can say the same thing about the original houses - many I've loved to near-death; some gave me the meh's.
I have faith in Orlando's creative team - just not so much faith in those that hold the purse strings, and therefore the whips. I understand the issues with presenting similar product to two different markets, so my concern I think comes more from Hollywood mis-judging marketing to Orlando (as Ryan has suggested before).
As always, this is only one woman's opinion, and YMMV
