Earthlings (2005) was life-changing for me, opening my eyes to veganism. A more recent version is Dominion (2018).

But these deal with a gruesome topic. Planet Earth (2006) is more suitable for “favorite”. It blew me away, because I’ve never seen wildlife footage like this before.

Now imagine there’s an outdoor barbecue and you’re a pig and the only person speaking up for you is disregarded by everybody else as a dysfunctional nutter.
