Death Note
The popular dark anime, Death Note, captures the story of a boy named Light who discovers a notebook with the power to commit murder by writing a person's name in it. He gets power-hungry and has a crisis of morality. Netflix decided to give the show a spin-off film starring Nat Wolff and Willem Dafoe, and critics didn't love it.
Entourage
Despite the popularity of the tv series, Entourage, the movie version felt weirdly like a special edition episode rather than a stand-alone story. The series was on the air from 2004 to 2011 and kicked off the careers of several stars like Adrien Grenier.
