I agree 100% Marc. Although all their rides are mediocre, there are a lot of them, and a few of them stand out as being quite different. This fits that perfectly - so FL hits the 'to do' list for 2009.
I like a well themed ride, it makes the queues a little more bearable, but unless the theming really interacts with the ride and adds a huge amount to it (I assume Mystery Mine fits this description), then it's ALL about the ride. Looking 'nice enough' is fine by me, especially for a park like Flaminglond
