Godzilla (2014) was pretty good, except for Muto having that electromagnetic pulse weapon. Why would a biological evolutionarily develop such a thing? It's useless against Godzilla.
Only useful against technology really, and that seems so unrealistic. That's where it lost me, the convenience of a creature that can EM machines. So unbelievable.
For Godzilla's return, the King of the Monsters was given a radically new origin story that deviates from the previously established origin of him being mutated by the hydrogen bomb: in Godzilla, Godzilla is explained by Monarch to be an ancient, radiovorous apex predator that has existed for millions of years, existing at least as early as the Pliocene period.
