If you go to war with the Mafia do you have to use Tommy Guns?
Mac Bolan is a one man army and he has the Mafia in his sights because reasons. And he gets the girl. I think that sums up the plot. Change Mafia for some other antagonist and you have the plot for the entire series of the long running young-men's action novels.
When I was young Indiana Jones was the prototype for action-adventure movies. They were amazing. It took a long time for them to be released on DVD, but when they finally did I grabbed them for a movie marathon. I was a little disappointed. They were cheesy. It was hard to tell if they were always cheesy or if they had aged badly because Indiana Jones was the prototype for a genre that had evolved and now looked lame in comparison. NB: don't take that as a diss on Indiana Jones.... except Kingdom of the Crystal Skull, which was terrible.
The Executioner is similar to Indiana Jones in that it was the prototype - well, one of many - for a genre that has evolved. It's hard to call this cookie cutter stuff since this was the prototype cutter. It is easy to see the appeal and how this influenced so many people, including my friend Matt Hilton (shameless plug). But so much time has passed since these were new. In that time a generation of authors, TV shows (watch Banshee), and movies have been influenced and created works. The genre has grown, matured, and taken on other elements, such that this feels kinda cheesy. Was it always cheesy? Maybe that was what made this series fun in the first place.
