Does it make me a bad person that when I heard the news I was disappointed it was a different Will Smith?Does it make me a bad person that I snickered when I read this?
On the subject of the characters joking around when they're in the Suicide Squad, the more recent versions I've read have all been dark humour centric.
I really like Harley Quinn in the comics, her personality is vitally important to how she goes over in this movie. Just because she doesn't sound like the version from a children's cartoon doesn't mean they won't get the character right.
