Yeah I like the original Dune very much too. But it's not a masterpiece. Just an underrated flick full of great actors.
But I will say this: even if you think 1984 Dune was meh, go watch Villeneuve's version with the most unconvincing Paul Atreides in the history of unconvincing actors (Timothy Chalamet), the appalling Lady Jessica with zero expressions and zero acting skills (Rebecca Ferguson), and Oscar Isaac as Duke Leto who manages the incredible feat of being as shit in Dune as he was in Star Wars.
Then watch David Lynch's again: you'll enjoy it all the more.
1600 patties per cow is a value I've heard since I was a kid in the 70s. It wasn't McD specifically. Maybe the cows have grown fatter or the patties smaller over the decades.
Anyway, my point was, hundreds of millions of burgers doesn't deplete the country of cattle heads. It was an remark about orders of magnitude.
