Why did child star Haley Joel Osment fail to cross over as an adult actor after he was hailed as a prodigy as a child actor?

I recall how he was widely praised as a child actor, the critics would wax glowingly about how good an actor he was, how he was unlike any child actor in the business.Truthfully, his performances in THE SIXTH SENSE and A.I. ARTIFICIAL INTELLIGENCE are among the best acting I've ever seen. I still think he deserved a Best Actor nomination for A.I.Yet after PAY IT FORWARD, it seemed like his career took a halt. He continued to act, in films like SECONDHAND LIONS and THE COUNTRY BEARS, and yet, the hype was over. Why?Was it because his acting wasn't as brilliant when it came from a teenager? Was it because he turned out unattractive as an adult?What is your theory on the downfall of Haley Joel Osment? via /r/movies https://ift.tt/h6kA0Ij
