He's talented but I can see why it takes people out of it having the same actor basically playing the same role in 3 different properties with just a few years in between. His role in this doesn't look any different from It or Stranger Things just based on the trailer. Still, it doesn't necessarily have to be a problem. Some people complain about typecasting but I'm sure this kid would rather take that than nevercasted.
His role in IT was very different from his role on Stranger Things.
