Dear comic-book blockbusters,
If you are going to be 'ironic' about pathos or 'self-aware' about sentimental plot machinations, please do not just immediately, directly, and shamelessly fulfill the conventions you are being 'ironic' or 'self-aware' about. At least pretend that you're going to do something else. Make the effort to fake us out even if it doesn't work. As it stands, one can see the stilted writing on the screenplay page: "Hit Girl smiles wryly as she blah blah blah."
Also, I would appreciate it if one would either be honest about it, or at least do a better job hiding the fact that your film is really a preview for your next film. Bald, shameless promotion in itself is almost refreshing because it's rare ... everyone (like this movie Kick-Ass) has to dress up their bullshit in layers of sonic rapture & slo-mo.
The fact that you made a movie that so deeply involved an 11-year-old girl in bloody violence is, however, commendable.
