Spoilers ahead for the ending of Joker. You’ve been warned.
There are countless reasons why the Joker movie has proved so controversial, from the baggage the character itself carries to the inflammatory statements director Todd Phillips has been making to the press. The movie’s ending adds fuel to the fire in spectacular ways, so let’s break it down and try to figure out exactly what it’s all about–and why it’s so contentious.
1. The plot thickens in the final act, though, as Arthur stumbles upon his now-dead mother’s belongings. On the back of one photo is the note: “I love the way you smile – T.W.” hinting that there was perhaps more to their relationship than the brusque explanation Thomas knocked Arthur back with (literally and figuratively) during the Charlie Chaplin screening earlier on in the movie. So that’s a possibility that Arthur might not have been adopted.
2. When Arthur was handcuffed and talking to the psychiatrist at the end he said “I just thought of something funny”,”but you wouldnt get it” then a flashback to Bruce Wayne on the crime alley with his parents dead in the ground and I found it wierd why would Arthur find this funny. There’s an ethereal, dreamlike quality to the whole sequence, leaving us unsure if any of the things even happened.
3. What if that ending scene takes place in the future where Batman already exists and got the Joker put in Arkham but somewhere before that (or while inside arkham) Arthur discovered that Batman is Bruce Wayne and realizes he created Batman the day he became the Joker hence why he finds it funny. That would mean while he’s incarcerated at Arkham Asylum, Joker figures out the identity of Batman. That’s the funny thing he realizes.
