Mindlessly following Chekhov's Gun, in my opinion, will always result in pulp fiction. Whether it's TV or novels, or movies. If you've stripped a story down to the bare basics, all you're left with is predictability that gives the reader an easy ride.
Not to say that's always a terrible thing. After a stressful day, pulp fiction can be the perfect way to relax. Most people have something mindless that they enjoy.
But it is incredibly rare that you end up with something truly great if you religiously follow the principle.
