To blame one actor for the success or demise of a movie is ridiculous. That franchise started it's down hill before Batman and Robin. Once the movies went away from batman being the dark knight and went with the tv series a lighter side of the Batman, that's when that franchise started to fold. George Clooney didn't do a bad job of playing Bruce Wayne. It was the direction the movie was headed. What if Clooney did the movie with Tim Burton at the helm. It would have been a completely different result.
