I entirely agree that the farm was tired and past its sell by - it had been under-invested in for at least 15 years (since the foot and mouth crisis) and was in need of a complete overhaul. I also appreciate that the re theme into CBeebies is very popular with young children, has breathed more life and energy into that area, drawn the crowds and thus the park deem it a success.
However.....in my opinion on a theming and general design level it was a bare minimum effort. The hands-on attractions (Mr Blooms Allotment, Kung-Fu Tom) are great and make fantastic use of previously underutilised space and the audio around the area is a smart touch. Yet, the main central area is aesthetically hideous - particularly the building exteriors and the central roundabout (which should be a focal point). There is practically no evidence of any quality craftsmanship or thoughtful or careful design in any of the areas theming. It is literally multi-coloured paint, cheap 2D vinyls/signage and an overload of bog standard quality plastic character theming of the sort found at any second rate regional park (except Alton has the premium IP).
In the 90's they employed theming artists to design two imaginary and thoughtful areas that children could enjoy and adults could appreciate. They even made hand crafted models for Storybook Land which demonstrated the level of care that went into the design. Fast forward 20 years and it's a case of buying an IP, sticking in character models, applying paint and adding the usual interactive malarkey. Although children may love it because of the recognition, I see very little that will inspire their imaginations (call me naive if you want if you have your own kids and know different). Pleasing three year old's at a theme park is not hard when you have an popular IP (again correct me if wrong?), but designing something that can be inspiring for children and appreciated and even enjoyed by parents and other adults requires a greater skill.
If I go back to the point I made originally around the lack of innovation and investment in non coaster attractions - Alton were way, way late to the game with bringing their children's offering up to scratch. Drayton Manor built Thomas Land a whole eight years ago and in the time since then we've seen Peppa Pig and Nickelodeon amongst others in the UK. Instead of acting like the market leaders they are supposed to be, they jumped on the kids IP bandwagon nearly a decade too late and even then have not provided an offering IMO that raises the bar in terms of attractions and overall quality. Smaller park's in the UK should be the followers, not the other way around.
So yeah - they paid for a sought after IP, applied bright paint and the result is a popular kids area. So what? If they can offer world class, world beating roller coasters then they can do the same with their family and children's offerings. The likes of CBeebies and Mutiny Bay are, IMO, barely above adequacy for a park of Alton Towers stature (rapidly being eroded I may add). I do however believe that the park has a greater issue with the number and quality of family ride offerings than with those for young children, but that doesn't excuse mediocrity.
