HHHmmm do we really need another "Parker" Film? and one with J-Lo at that?

So here's the trailer for Parker. Looks typical, what you may not know is that the title character Parker is from a series of crime novels and has already had some pretty good/fun Films based on the character (notably Point Blank & Payback) Jason Statham is no Lee Marvin, heck he might not even be able to match Mel Gibson. This seems pointless.
