I don’t personally think Thorpe is really trying to be a family theme park anymore, and I don’t think that’s necessarily a bad thing. There are many parks out there that have succeeded in being thrill parks, including in Europe, and I think Thorpe has definitely made good steps towards following in the footsteps of these parks, personally.
I think the main difference between Thorpe in the 2000s and Thorpe now is that while the rides being installed were very similar in terms of caliber and target market, the themes were almost a little more whimsical under Tussauds (I’m not sure if that was the right word?) and didn’t take themselves too seriously. Even though they were aimed at thrill seekers, things like Tidal Wave, Stealth, Nemesis Inferno and to a lesser extent things like Colossus don’t have overly serious themes; they do almost have an element of light-heartedness about them, in a way.
Contrast this with the investments under Merlin; besides Storm Surge, Angry Birds Land and I’m a Celebrity, which were all aimed more at families, a lot of the park’s additions have very stark, gloomy themes that are more upfront in being dark. Things like Saw, Swarm, DBGT and Walking Dead are all quite stark, serious themes that I think do change the tone of the park a bit. I’m not saying that Merlin’s themes are inferior to Tussauds’ (far from it, in fact, as I think much of Merlin’s theme work at Thorpe has been absolutely fantastic) but they do create a somewhat different tone to the themes that Tussauds created.
For the time being, I do think Thorpe has a sufficient amount of family attractions given the target market of the park, personally, although maybe some kind of other major family attraction might be a nice addition in the future to round things out a little.
I accept that opinions will greatly differ on this, and I totally accept that most people have different tastes in theme parks to me, but I certainly don’t think Thorpe need to go back to being a “family dreamworld” like they were in the 80s and 90s, and for one sole reason; if you look at this in the wider context of the UK industry, Thorpe is one of very few parks in this country that still actively targets thrill seekers (the only other two I can think of off the top of my head are Alton and Blackpool, although Flamingoland may also be worthy of a mention given the coaster being built for 2021), and is arguably the only one has lenient enough planning restrictions, sufficient money and sufficient space to really do the “thrill park” concept justice. By contrast, “family dreamworlds” are extremely common in this country; even in the M25 cluster alone, you have Chessington and Legoland a stone’s throw away, and Paultons isn’t too far either. Most of the country’s independent theme parks seem to have gone down the family route as well, so Thorpe can sell itself and make itself unique far more effectively as a thrill park, in my opinion.
