A good effort, with some decent acting, creature make-up and some interesting sets, but sadly lacks any kind of humour, spontaneity and all the things that made TV series like Knightmare, The Crystal Maze and even Fort Boyard interesting and fun to watch. It's far too polished and controlled by the producers and is in no way "immersive" as they claim to be. The stakes are so incredibly low. There is literally nothing to lose here other than the plot of the storyline. There are no prizes to be won. The contestants are therefore not much more than glorified actors that occasionally must solve puzzles - the rest of the time they're told what to say and do. Plus there's far too much post-production work that further drives home that this is highly controlled, cheap way of getting a knock-off fantasy series that's disguised as some kind of real-life puzzle adventure game show. It doesn't know which genre it wants to be in.
