Brilliant post CGM!
Merlin don't theme everything in a dark, run down way. Look at their family additions. Nothing not thrill related has had a dark theme. Clearly, dark themes suit British thrill rides. Obviously why Thorpe is just filled with depression.
My point is, that it's unfair to say Tussaud's did a better job, seeing as all their thrill additions were dark/run down in some way.
I know you go to a theme park for fun/escapism, but if the average thrill seeker gets excitement from close calls with death etc, then the ride will mimic those needs.
I expect it is cheaper to maintain, but that won't be the sole reason behind the theming choice.
Of course they don't give family/kids investments a dark theme. That's just common sense, you can't go having a dark and sinister kids area that the kids are going to be too scared to enjoy. Thankfully with CBeebies Land for example, Merlin were forced heavily by the BBC to ensure things met high standards.
Dark themes do naturally suit thrill rides, that's pretty obvious. However doing it time and time again demonstrates a lack of creativity. But it is not that the themes are dark that is the major problem, it is the manner in which these dark themes are done. Dark does not have to mean run down, it does not have to mean a big warehouse, it does not have to mean aged. But let's look at Merlin's UK examples:
- Mutiny Bay: a darker theme than Merrie England, was actually done well in the early Merlin days but upkeep has been almost non-existant, but they get away with it somewhat due to the theme
- Saw: dark theme done well as matches films, one of their first coasters, no complaints
- Thirteen: dark theme for a family thrill, ride itself not too bad. But Dark Forest; basically a run down derelict version of Ug Land that has aged terribly
- Wild Asia: not a dark theme as such but still mostry grey colours that are easier to maintain, do no look so bad when ages and weathered
- Nemesis: Sub-Terra: basically a big metal warehouse, easy to maintain
- The Swarm: some great theming pieces but all damaged/derelict due to nature of theme. Means they are able to age poorly with little impact on the overall theme
- The Smiler: should have been a dark theme with a more 'clinical' look yet we ended up with tonnes of filthy concrete that they have never even attempted to clean properly since construction
- Thorpe 2016: run down derelict warehouse, same old story
That's pretty much all of Merlin's major investments in their UK Resort Theme Parks (with the exception of CBeebies Land). However you say that these dark run down themes must suit the average British theme park goer. Well why is it a very similar case for Merlin parks in Europe?
- Raptor, Gardaland: a dark theme done very well. Can't comment too much on how it as aged and whether the theming lends itself to natural aging
- Krake, Heide Park: dark theme, buildings appear somewhat derelict.
- Flug der Dämonen, Heide Park: dark theme, dark building etc
- Gardaland 2015 Dive Coaster: appears to be yet another dark theme although we do not know the exact stlyle they are going for
So it is not just a UK thing. It is a Merlin thing. Not all dark themes actually have to look dark, sinister, aged or run down. Wodan arguably has a dark theme but looks impecible. Then not all thrill rides even have to have dark themes. Rita and Air at Towers were brighter themes when they opened. Blue Fire and Silver Star at EP. Khan and Shambhala at PA. Helix at Liseberg. Griffon, Alpengeist and Apollo's Chariot at BGW. They are just some examples I know first hand are out and out thrill yet their themes are not dark, are very presentable and look fantastic!
Merlin have almost turned the whole of Towers and Thorpe into these dark theme parks. You lose a sense of adventure. Dark themes everywhere does not equal magic. It's almost certainly one of the reasons as to why I now much prefer parks such as Disney and EP over Towers. You will see this in time.
