Reason for and circumstances of his family's death are so absurd...
In the comics, it's simple and understandable. His family is murdered by mobsters because they were witnesses to a crime and this sets him on his vigilante path.
In Emo Punisher, his family is murdered in some elaborate plan because Frank was part of a secret unit whose officers were drug traffickers and they killed his entire family because killing him alone quietly would somehow cause more questions? From who? These same people then later sent a death squad to kill someone else in his unit who knew about the trafficking. I guess for some reason this wasn't going to raise questions with the same people they were afraid of? Why would they have waited so long to go after Gunner when he actually knew about what they feared Frank might find out about? And this is all because they were afraid Frank (Before he was The Punisher) would find out and get all pissed about the trafficking?
It's just so ludicrous when you think about it. They couldn't just keep to the basic story that makes sense, it had some big convoluted situation involving war crimes and CIA crap. I think Frank going after mobsters and criminals would be far more interesting.
