Ryan Reynolds as Green Lantern
It is pretty notable that Ryan Reynolds has been miscast as major superheroes not once but twice, as Deadpool in the first Wolverine film and as Hal Jordan in Green Lantern. Both were awful, but Green Lantern definitely takes the cake. Reynolds is completely devoid of the charm and charisma of the character of Hal Jordan, and it shows SO much. It doesn’t help that the movie is 95% CGI, which would challenge even the best actor, but it would have helped if he were… well, even a good actor. Why wasn’t Nathan Fillion cast, anyway?
