Full disclosure: I normally don't watch variety shows but I watched this because Yeo Jin-goo is in it. But by the end I was charmed by all the participants in this cooperative reality show: Ha Jung-woo, Joo Ji-hoon, and MINHO too. There were a lot of touching moments of bromance as well as mentorship from the older actors (Jung-woo and Ji-hoon) to the younger ones.

The crew also really set the cast up for success. When their initial ideas for the formula of, e.g., the variety show challenges didn't work out so well, they made changes on the fly and took lessons learned to get it to work out next time. Everyone had good humor and was flexible. You can tell everyone involved was trying to make it a good experience for each other (so different from American reality shows).

Also if you are a big fan of any of the cast members, you will learn a lot about them, their attitudes, and their histories from this show, so it's good to watch for that reason alone.
