Short version: gloriously absurd.
Slightly longer version: Do you want to see giant monsters smashing the energy blobs out of each other? Do you care how the monsters got there? Do you care how you got there? Do you feel the urge to shout TOO MANY QUESTIONS MOAR KONG AND GOJIRA right now? If the answers were yes, no, no, and NO MOAR TALK, then: welp, then go ahead and watch GODZILLA VS. KONG. it’s just what it says on the label.
I had a blast.
PS: This movie name-drops a remarkable number of Golden Age conspiracy theories. Except for all the ones about the Jews, thank God.
