re: Is Robert Pattinson judged only by the Twilight series?

Is he a great actor?

Meh. I don't know. He isn't the drizzling poo. Sure he gets his ration of abuse for the Twilight series but there is no shortage of good actors who have been in terrible movies.

Here is the key to casting Batman. Cast someone who takes the role seriously and accepts they might be the third or fourth most interesting character in the movie. George Clooney giving a "wink, wink, nod, nod" Batman was horrifically bad.
