Edit - To give some personal context, I was thinking about the thread the other day where Snyder fans claimed that good movies are 4 hours long and then I saw this picture. Throw in the crap like baby yoda knockoffs and expanded universes and it's all so bad.
Letterboxd is actually somehow useful in this way. Even though they basically made it as a social media platform for reviews, you can find even more critics you agree with and just follow them. I genuinely don't know that many big name critics either, but it was really fairly easy to find people on Letterboxd that share my same idea of a good movie
