Simply put, this movie is no masterpiece and if you think it is, you need to see WAY more movies. And by way more movies, I mean movies that aren't superhero movies. The funny thing about all the people who call this movie "a masterpiece" is that they can't qualify that claim in any way. Try it for yourself - ask the next person you talk to about Joker why it's a masterpiece. If you're lucky, you might get a response that goes as deep as them saying something vague about the writing and directing being amazing. Ask them to explain that. I guarantee you they won't be able to. This movie is one note, from beginning to end. Joker is crazy at the start, and crazy at the end. There is zero nuance, subtlety or character development. He simply goes from being crazy to crazier. It is cynical, lazy and a dull retread of the REAL masterpieces (like Taxi Driver and King of Comedy) from which it shamelessly steals (poorly, I might add). Beware of anyone who calls this a masterpiece, they have zero understanding of cinema.
