Cringey aspects of Godzilla...
Well, in most cases, Toho's international dubs are just the worst. My first exposure to these were the 90s Heisei films and I was amazed at how horrible they were. It sounded like they hired one guy to do all the male characters and one lady to do all the female characters. And then when I got around to seeing the international dubs for films like Sea Monster and Son of, I gained a whole new appreciation for the dubs I grew up with. Yikes!
As for the fans, yeah, there are some embarrassing fans out there, but I feel that is true of any fandom. Let me count the ways with my other hobbies and interest:
Star Wars: SW fans can be horrible, especially the new age ones. They are always either complaining to the nth degree or defending it with religious zeal. There is no in between. I have been called both a Nazi and a cuck by two sides of the Star Wars fandom because I didn't completely love nor completely hate The Last Jedi. Turns out the middle ground gets everyone to hate you.
Star Trek: Actually not as bad as others, despite the reputation, but if you've seen the really really REALLY geeky Star Trek fans, you know how awkward they can get. I've met some really awkward nerds in the Star Trek fanbase, but I've honestly never had a bad experience with any of them. I think the worst I've ever had was one calmly and awkwardly trying to explain to me why Insurrection wasn't that bad.
Pro Wrestling: I don't have enough time in the day to explain to you how bad wrestling fans can be. If I hear the words "work rate" and "star ratings" ever again, my head might explode. God forbid I enjoy a Hulk Hogan or a Hacksaw Jim Duggan match. No no, by all means, tell me how every Japanese match ever held is the greatest match of all time (BTW, I do enjoy Japanese wrestling...I just hate the way fans talk about it).
Sherlock Holmes: Okay, well read Sherlockians who love the original stories by Arthur Conan Doyle? From my experience, mostly great, smart, and charming people. Younger fans that have only seen the Cumberbatch version and want Sherlock and Watson to have sex with each other because apparently, that is more important than solving mysteries and just go on and on and on about how hot everyone is/supposed to be....excuse me while I bang my head into the nearest brick wall.
Comics: The comics fandom has gotten so terrible, I find myself avoiding discussions about the medium altogether. Just super toxic. And I guess it has always been that way, but back in the day, I could deal with the ubernerds and nowadays I can't stand being around them for more than 5 minutes. Maybe I'm just becoming a curmudgeon in my old age. Damn kids! Get off muh lawn!
Animation: This covers a lot of ground, but the adult fans of animated cartoons today scare the hell out of me. I mean I've never seen Steven Universe, but I've seen how its fans act like rabid animals. Now they can act terrible with their own thing but please don't infect the things that I like...oh wait, we're getting remakes of the shows I grew up with Thundercats, Ninja Turtles, and She-Ra and all those weirdos are jumping on those bandwagons...well...poop. I am also freaked out by how they weirdly sexualize children's cartoons. When I see the weird fan art, cosplaying, and just general behavior of fans of shows like Steven Universe, My Little Pony, and all of those other kind of shows, it raises an eyebrow from me. And these are adult fans, so them sexualizing children's shows is just doubly unsettling to me. I mean I remember their being some weird sexualization in the Thundercats fandom back in the day, and it bothered me, but it is nothing compared to what I see nowadays. Its at a point where if I had a young daughter and she wanted to go to a My Little Pony convention, I'd say hell no because she'd be surrounded by 40 year old men with dolls that they, uh, do stuff with.
and more specific to animation -
Rick and Morty: I watched a bunch of people that like the same TV show as me hold protests in McDonalds restaurants across the country because they didn't get their McNugget sauce. I have never been more embarrassed to be part of a fanbase in my life.
Compared to all of that, my experiences in the Godzilla fandom have been relatively mild. There are embarrassing moments and fans here and there, but not to the degree of everything else I've dipped my toe into.
