I'd take an R-Rating too, I mean it never took off with kids anyway so why not bring it back? Also agreed, if going along the lines of the first movie it doesn't suit a PG13. I'd still watch if it was PG-13 though.
Classic suit or very much resembling it too.
As for the Nancy comments, she wouldn't need to have a major role like being his partner, she could be higher up now but still have some involvement with him. I'd like her character to be in it anyway.
So far as what we end up with, I didn't like everything that came after the first movie anyway so it can't be worse (don't want to jinx it)
I'm going to let myself feel a little excited for this for the time being
