It used to be a great show. However, after watching the first episode of season 2, I have to admit that I lost my interest.
This has primarily to do with the flaws that were there in season 1 being justifiable because of it being just that, the first season.
However, as season 2 is here, a lot of these flaws remain, like the already overly named "fake cheering".
But on top of that comes the changing of countries and commentators, and while Charissa Thompson and Terry Crews had clear chemistry that made the comments a joy to hear, Chris Distefano and Tiki Barber are rather... well... they are there, but don't truly add anything. Also, the Italian commentator Bianca Balti is so emotionless that it is plain annoying; she could take an example of the Chinese Qinyi Du.
As for the countries, I actually wonder why they don't change the countries every episode, as it would make the finals far more interesting to watch, as it would have actually to do with the countries, and the one winning would actually be the ultimate beastmaster. Now the one winning season 2 will be ultimate beastmaster of the USA, India, China, France, Italy and Spain, while the one of season 1 is the one of the USA, Brazil, Germany, Mexico, South Korea, and Japan; They are not true ultimate beastmasters, only of a few countries...

Regardless, if you don't mind the faking, are able to look beyond the countries, and think the commentating doesn't have to be good, than it is worth the watch, but if you are like me, you will probably have an aching feeling of annoyance...
It's too bad, as the idea is great, but the execution just really lacks...
