I wasn't sure if I wanted to watch Down to Earth because I wasn't sure how I felt about Zac Efron. I thought perhaps it would border on being too light hearted or cater to a teeny bopper type mentality. I was so pleasantly surprised! I have a new formed respect for Mr Efron. I felt he was very sincere on learning more about sustainability and what is good for our bodies.The first episode in Iceland is super cool but a tad slow. All the rest of the episodes were so good. I hope you watch it. I honestly think you will be glad you did.
