That's tough line to teeter on in an action film, of course. But I think this is the type of tone that would fit these characters. If anyone hasn't seen ESCAPE FROM NEW YORK, this is how I look at it: Suicide Squad should be the bastard child of ESCAPE FROM NEW YORK and KILL BILL. It should be a group of colorful over the top characters (Like in the KILL BILL films) that to one degree or another mirror Plisken's attitude. They don't want to be doing what they are doing, but they will do what ever it takes to get out of their situation alive.
If at least ONE scene in SS can match the tension of the bar scene in INGLORIOUS BASTERDS I will be a happy man.
