In an ideal world, Merlin will eventually transform it into an attraction with an original theme. I'm sure that half of the budget for Charlie was simply just to secure the rights and as of a result the lack of money gave us the poor quality attraction we have. So unless you have a s**t ton of money, I wouldn't go for any IP if it means the final product looks bad, they're simply more trouble than they're worth IMO. Then again this is Merlin so I'm not holding my breath, they really seem to do things the hard way.
