I completely understand how some people would absolutely love Citizen Kane. There are people who are much more into the production and artfulness of movies than I am. Everyone has their own reasons for liking or disliking particular movies (or anything else, for that matter!) As a non-student of film making, I pay less attention to how it is made. For me, I just want a movie that holds my attention due to the plot, acting, and writing something I can relate to. I am a simple man who likes a bit of emotional escapism. Certainly, different eras have different ways of doing this.
As an example, I enjoy watching reruns of Adam-12. The acting in 1960's television shows was dreadful, but the show somehow still compels me to watch.
