Good enough, but why doesn't "Joker" become a masterpiece of film history in my personal standards?

Arthur Fleck: [Arthur goes to Wayne Manor where he sees young Bruce and does a clown rooting form before talking to him through the gates] Hi. What's your name?

Bruce Wayne: I'm Bruce.

Arthur Fleck: Bruce. I'm Arthur.

[He sticks his hands through the gate, puts his fingers on Bruce's face lifting the corners of his mouth as if to make him smile]

Alfred Pennyworth: Bruce! Bruce! Get away from that man.

Arthur Fleck: It's okay. I'm a good guy.

Alfred Pennyworth: How do you do? Who are you?

Arthur Fleck: I'm here to see Mr. Wayne.

Alfred Pennyworth: Well, you shouldn't be speaking to his son

[Giving back the fake flowers Arthur gave Bruce]

Alfred Pennyworth: Why did you give him these flowers?

Arthur Fleck: No, they're not real. It's magic. I was just trying to make Bruce smile.

Alfred Pennyworth: Well, it's not funny, is it? Do I need to call the police?

Arthur Fleck: No, please. My mother's name is Penny. Penny Fleck. She used to work here years ago. Can you please tell Mr. Wayne I need to see him?

Alfred Pennyworth: You are her son?

Arthur Fleck: Yeah. Did you know her? I know about the two of them. She told me everything.

Alfred Pennyworth: There's nothing to know. There is no "them." Your mother was delusional. She was a sick woman.

Arthur Fleck: Don't say that.

Alfred Pennyworth: Just go. Before you make a fool of yourself.

Arthur Fleck: Thomas Wayne is my father.

Alfred Pennyworth: [Alfred starts laughing, causing Arthur in anger to put his hand through the gates around Alfred's neck and starts to choke him] Let go of me! Let go! Let go of me!

[Arthur looks at Bruce watching with fear, he turns and runs off]

Detective Garrity: Mr. Fleck. Sorry to bother you. I'm Detective Garrity this is my partner, Detective Burke. We have a few questions for you, but you weren't home. So we spoke with your mother.

Arthur Fleck: Oh. What did you say to her? Did you do this?

Detective Garrity: What? No.

Detective Burke: No, no, no. We just asked her some questions. She got hysterical. Hyperventilating, collapsed...

Arthur Fleck: Yeah, but the doctor said she had a stroke.

Detective Garrity: We're sorry to hear about that. But like I said, I still have some questions for you. They're about to subway killings that happened last week. You've heard about them right?

Arthur Fleck: Yeah. It's horrible.

Detective Garrity: Right.

Detective Garrity: So we spoke with your boss, over at Ha-Ha's. He said you were fired for bringing a gun into the children's hospital. Is that true, Mr. Fleck?

Arthur Fleck: It's a prop. It's part of my act. I'm a party clown.

Detective Burke: All right, so why were you fired?

Arthur Fleck: They said I wasn't funny enough. Can you imagine that? Now if you don't mind, I have to go take care of my mother.

Detective Burke: Your boss also gave us one of your cards. This condition of yours, The laughing, is it real, or some sort of clown thing?

Arthur Fleck: A clown thing?

Detective Garrity: Yeah. I mean, part of your act?

Arthur Fleck: What do you think?

[Arthur turns and starts walking towards the hospital doors, but walks into the glass door]

Detective Garrity: It's exit only.
