Honestly, I never knew Chadwick had so many fans. He was just ok as Jackie Robinson & James Brown. He was good as Thurgood Marshall (movie was ehhh) and in 21 Bridges, but forgettable in Gods of Egypt and MCU movies besides Civil War...and maybe captivating in less than 1/2 of his TV appearances...at least the ones I saw...Fringe, Lincoln Heights, Castle, Cold Case..
He was a good actor and a seemingly even better person. He was like Ledger in that he passed before his potential was fully realized and also like Heath his last performance was his best(Ma Rainey).
