Without any context? how about the murder of Israeli athltes in Munich? Isn't that context enough? Too bad, 'cause that's the picture most people would want to see. Instead it will be a more 'nuanced' portrayal where the concept of 'evil' or 'bad' is nonexistent. In other words, watered-down garbage.
I have seen this movie before. It was Black Sunday where Robert Shaw and another actor play a couple of Israeli agents and they have an angst filled moment questioning why they are going after terrorists. Fortunately the moment passes and they save the Super Bowl in the end.
