Honestly, I thought he was decent for what little he was in. However, whenever he's brought up regarding this movie, I'll always remember two things.
One is his cringe-worthy method acting tactics where he reportedly blinded himself with contact lenses so he could understand the character better, even though it was a really small part, and the other is that the role was originally written with David Bowie in mind and went to Leto after his unfortunate passing in the dreadful year of 2016. He would have been a perfect fit, but alas...
