The Difference Between Enjoying a Film and the Film Being Good

I feel as if most people get the difference between enjoying a film and the film being a good one confused. I used to do the same thing. Everyone does at some point. One can enjoy a film even if the film itself is awful. For example, action packed films are always really fun to watch because of all the fight scenes and the explosions and the special effects but really, is the film that good? Take away all of the special effects, what's the story to it? It seems like it's all action. There sometimes is no true plot. You may even start to question why there a fight sequence actually occurred and how it really didn't need to be in the film. Films may be fun to watch but at times, the film itself may not be good.
