I'm not sure what you mean, nobody was complaining about the musical before they saw it or how successful Nick Hutson (or whoever else) is, dont think that has anything to do with it
Anyway I watched some of it, I was excited to see what strange creation it could be and enjoy it as a bit of lockdown fun. But to be honest it just felt like a drawn out in-joke /self promo for a small group of Twitter fans, I didn't find it very entertaining or anything to do with theme parks. Props to putting it together but whats the point if it's not for anyone.
