Here you go! Let's put this into perspective ...
My take ...
* Godzilla looks better in the 1962 film. Always standing up. He looks much more different in the 2021 film. I've never seen him crawl on all four limbs horizontally. Then when he stands up then you know he's Godzilla.
* King Kong looks better in the 2021 film. Facially much more like a giant gorilla than in the 1962 counterpart.
Historical accuracy ...
I do like the prehistoric premise that the 2021 film takes. Explaining the origins of King Kong and Godzilla's early descendants.
Alright, so there are United States Navy destroyers, cruisers, and battleships in the 2021 version. In the 1962 version, the Japanese Army and Navy along with a U.S. Navy submarine. I'm okay with the U.S. Navy's destroyers and cruisers in the 2021 film. But battleships? Those things were all decommissioned after the Gulf War in 1991.
