Tim Burton’s Charlie and the Chocolate Factory (Warner Bros., 7.15) is tracking very big. The trailer makes it groaningly clear this is one of those heavily painted, what-you-see-is-what-you-get films…which American audiences have alway tended to wet themselves over. I guess I’m different because it definitely gave me pause. Is Burton over? Is it fair to ask if he has another Ed Wood, Edward Scissorhands or Beetlejice in him? I wonder.
