I really hate these cooking competitions where, halfway through, the judges throw a change into the mix. "Not only do you have to do in 6 hours what you'd normally do in 20, now you have to make something that dances and spews fireworks!" Or something like that. Just seems unfair and borderline sadistic, especially when our requires a complete pivot to design or baking. So can you guess what happens to the contestants in the middle of this one? Beyond that, it's nerve wracking watching some of these with the hoops they make them jump through. Well filmed and edited, great sound and music, cool judges and hosts.
