Welcome to Erf, as I like to call it. Anyway, nature documentaries are not really my thing, but I gave this a chance because it's Will Smith. Overall, I thought there were some entertaining moments, although sometimes it would focus on scenes where Will Smith wasn't a part of, and it got less entertaining to me. Regardless, the visuals were absolutely mindblowing, especially in HDR, so that's a good enough reason to watch it alone imo.
