Re: Europa-Park 2014: "Arthur" - Suspended Powered Coaster
The fact that it's not a very well known film makes it the perfect IP for me!
What would you rather have, a well known bluckbuster of an IP which gets shoehorned in so that shareholders can see a decent uplift in gate sales for a couple of seasons, or a lesser known, subtle IP that is planned years in advance and will be perfectly blended into an impeccable well managed park?
If a theme is done well the IP just doesn't matter. I hate Harry Potter, but I thought HP land at IOA was incredible. My knowledge regarding the story, characters etc was very limited but I was still able to appreciate the area. You don't need to know anything about Dr Suess to enjoy Suess Landing, you don't need to have seen Jarassic Park to enjoy River Adventure, you don't need to be a comic fan to enjoy Marvel Island. IOA is a great example of themes where knowing the IP can provide some bonus content for fans, but not knowing it doesn't detract from the guest experience.
I've not seen this film (or whatever it is,) but I expect that I'll walk through EP and go 'O, were in the magically forest pixie land now, cool." It sounds silly but over the years I've learnt that the best way to enjoy a park is to take my enthusiast hat off and enjoy my visits on a much simpler level. I leave all the analysis and nit picking for when I'm back at home in front of the computer.
