So I guess you must have really hated Ewan McGregor as Obi-Wan Kenobi in Star Wars
, or every single Doctor after the First Doctor in Doctor Who
, too? Those were all original characters "made" by the actors that first played them. But they were hardly the only
ones to play them and hardly the only
ones to be enjoyed by large numbers of people.
To put it simply, you have no way of knowing if you're going to like a new actor's portrayal until you actually see it. It's the very definition of ignorance to assume otherwise.
