Welcome the the Shard! I'd suggest introducing yourself in the Introduce Yourself thread!
In regards to Joker: I did see it. I thought it was a great movie that really opened up about mental health. It had its flaws and controversies but I applaud the bravery for releasing it.
That being said, it's a great movie but I don't think it's a great Joker movie. If this was released without the Joker involved and another character then I don't think it would be doing as well.
