Soooo... yikes. I watched the whole thing in a day. I only planned on checking out the first episode based on a recommendation and I couldn't stop until the final episodes credits rolled. This is like Survivor, Ninja Warrior, and capture the flag combined, but jacked up by the teams being comprised of emergency-/combat-trained groups.
I definitely rooted for one group or another throughout the show, but I kept having my expectations and hopes dashed and re-set. The irregular format of the episodes definitely played a part in making it hard to put down, but I'm not even mad. It was so enthralling that I didn't want to stop. If I started an episode saying "this is the last one for the day", I ended it saying "No, the next one will be".
Now I just want to see other countries follow South Korea's example with this show. This could become international with the best groups, or best combinations of players amongst a country's groups, to compete with others.
South Korea has quickly become an extremely serious contender amongst global entertainment hubs, penetrating America's previously/seriously uncontended coast-to-coast empire. Yet, as an American myself, I am delighted by both the (friendly) competition, and a better look at another culture through reality TV, film, music, and more!
Countless Americans are both energized by and excited for more South Korean entertainment. Keep going. What you're putting out for the world is amazing and it's earning more and more appreciation with every year, movie, show, album, etc.
We love you.
