This movie was a relief to watch after so many increasingly overcomplicated, bloated Godzilla movies that were admittedly fun, but felt very 'brain-popcorn-Marvel-slugfest-with-fireworks.'
The historical and cultural problems of post-World War 2 Japan were beautifully prominent, and the cast was diverse in their acting and how they presented themselves. There was a beautiful darkness and seriousness to the movie, balanced with blatantly human moments and true-to-life moral struggles and emotional outbursts (and a sparkle of snark and silliness to make it tolerable). This captured the essence of what modern big-Hollywood movies are missing. It felt so raw and real, despite the fact that the main 'enemy' was a 300-foot radioactive lizard. I don't want to spoil the plot, but this was well worth my $14, and I'm going to take my family to see it.
Also, this was probably the scariest Godzilla following Shin. It's just... creepy and predatory in a way I can't describe, I love it.
As a followup, the director was also one of the VFX artists and it only cost $15 million to make (and 15 million in movie money is microscopic). Excellent movie made under impressive circumstances.
