From what I can see it’s a new take on an old story similar to the way that Chris Nolan re-imagined Batman or Guy Ritchie with Sherlock Holmes.
Some have criticized the movie because Daniel Radcliffe’s character of Igor doesn’t have a hunch back and seems to be a very competent assistant and character but I think it looks great. I’m a big fan of both lead actors to it gets an 8/10 on the Kitty Catnip excitement scale
Also if you haven’t seen it… Daniel Radcliffe has an excellent movie on Netfilx…. “Horns”
