Honestly
Colossal is one of the best American Kaiju movies since the 50's. It understands it's themes, it's capable of presenting a tone that goes from silly and full of jokes to something that's more dramatic and desperate, and, just like a lot of the original Japanese Kaiju films, it understands that the Americans were the real monsters all along.
I also think that the criticisms of the flashback scene in Colossal were overblown. Like, sure, I guess we didn't
need an explanation of how or why Anne Hathaway can make a monster in South Korea and have it mimic her moves, but the film isn't as bad for having that scene as the internet has claimed.
Pacific Rim comes at a close second, mostly because it's able to effectively switch to whatever tone it wants at a drop of a hat without completely losing the audience. (But, for me anyway, it also has the same effect on me that
Jurassic Park or
The Princess Bride has, where I'll also consider it the "Best Move Ever Made" only during the exact moment I'm watching it.)
Godzilla (2014) was the most visually impressive American Kaiju film, all things considered. While KotM certainly has more action throughout, the set pieces themselves don't feel as earth-shatteringly big as the 2014 film made them out to be. If GvK really wanted to go for that quippy tone, then they should have built the movie from the group up as being a mockery of the rampant Capitalism-at-all-costs-via-the-television/whatever-industry mindset that the original 1962
King Kong vs Godzilla film was. Or going for the tone in
Ghidorah, The Three-Headed Monster wouldn't be a bad idea either. (Can you imagine the kind of quips you'd get from a pair of small Shobijin girls that speak in unison? "Godzilla, what terrible language!" would only be the
start of all that!)
Honestly, we could have had a pretty good run of MonsterVerse movies continue from all this if budgets were kept at around $60 million like
Gendo's Papa said. But, for some reason, we live during an age where studios have to post on the biggest investments making the biggest returns, so I guess we're just not going to get nice things in spectacle filmmaking until they get out of that phase.
