This precisely, there has been a little bit of waiting for Thorpe to mess up again in everything they say or do. Now it really doesn't help that they have done so fairly regularly in the last year, along with seeding some of this through their own "banter". But some of the more positive stuff has perhaps been missed.
I've said somewhere in one of my many speculation posts this week, that I wonder if the park isn't going for a slight fresh start, or at least a restart on certain aspects. Improving quality and openness with guests has, it seems to me, slowly but surely been happening in the background. These videos wanted to show off how much work the park does over winter. The mere fact that the turnstiles are closed doesn't mean the park is just sat vacant. Additionally, various new information has been added to the support website, including an actual temperature at which most of their rides will stop at (it's 5c). A lot of things I've seen asked for on this forum have appeared in Thorpe's output this year.
So if they're doing these small changes, then I hope that's also happening on a bigger scale across the park. The rides have all been shown to get some serious work this year. How much in comparison to other years? Well we'll have to wait for Thorpe Park Winter Updates 2019/20 to guage that.
