So...anyone else watching this?
It's a little bit American Gladiators (minus the Gladiators) and a little bit Double-Dare for Adults (but only physical challenges, no trivia questions)...Was surprised to see Stallone host the first episode, but haven't seen him since (I think considering the title it would have been cooler to get Marc Singer, but Stallone is probably a bigger draw internationally). 108 competitors from 6 nations (9 episodes with 12 participants each, and a 10th episode as the finale), compete in various obstacle courses to see who is the "Ultimate Beastmaster". The oddest thing is there are also broadcast teams from all 6 nations, and supposedly you can watch the series from the POV of each broadcast team (although I've only seen the English and Spanish ones show up so far) .
My kids enjoy it, I kind of take a tongue-and-cheek approach to watching it, and the announcers are certainly good for laughs. Only watched 3 episodes so far. I'll admit based on description alone I don't think I would have watched this, but it is fairly entertaining.
