Zac as a bro in awe of nature and sustainable living* is pretty entertaining. I think this show gets a lot right, but there's also a fair amount of pseudoscience mixed in, which detracts from the impact and goals of the show.

It's like Entourage, but with zack and his bros doing things like... eating bread, talking to each other from across the boarder 15m apart, and hanging in hot tubs. I think if you're into zack efron this is the show for you. Not much going on.
