Enjoying A "Horror" Film

Can we really be 'Art-Horrified' by films made as far back as 1933? In films such as "Nesferatu" and a handful of others, the answer may be yes. But with the viewing of "The Invisible Man" with the famous Claude Rains, I must admit I was not.
One can see the formula for the typical horror film be unvieled. The stages are all there. A mysterious being presents itself, looking like a bundled man, but many villagers shy away from him as he enters the local inn, for no obvious reason. This man asks for a room as tries to keep himself concealed from the public at large, but is discovered by a well-intentioned but annoying innkeeper. This begins the discovery stage and a short "hesitation" ensues, while the villagers at large begin to see the "man" for what he is.
He is a scientist who injected himself with a rare chemical to achieve invisibility. While he realizes his goal, he is unaware that this same drug will eventually turn him to "white marble". The audience is informed through conversations with a colleague of "Jack" (the invisible man.) We learn a lot by this technique, as Jack's colleague is also the father of his girlfriend, Flora.
Flora is trying desperately to find Jack, but he wants to stay hidden until he is able to work out how to undo the effects of the drug, monocaine. (Is there any relevance to this name?) Meanwhile, the innkeeper tries to evict Jack and is assaulted. That is enough to bring in the police, which leads to another altercation and eventually a death. Jack has now emerged as the "monster" and the confirmaiton stage is intact. He is totally involved with finding a solution to his problem. He remains at large by simply removing his clothes and thus becoming invisible.
Jack seeks the help of another colleague, who is also in love with Flora, and feels threatened by Jack's presence in his home. His solution is to call the police, but first he calls Flora's father, who arrives immediately before the police. Flora wants to talk to Jack. He presents here as a concerned and loving man, but soon leaves Flora upon the arrival of the police.
While trying to elude the police and public until he can resolve his dilemma, he is discovered by a farmer in a barn. His breathing gives hime away. The confrontation stage begins, and Jack is shot while trying to run away. He is betrayed by his footsteps.
While he is dying, his physical self reappears, and here we see an attractive man, not a monster at all. But I believe there is a social comment there about the ability of everyone to be deceitful and single-minded about their goals, yet still be human, as is revealed int he final stages of Jack's life.
This plot seemed very obviously the 'Over-reacher' plot of the mad scientist, trying to become more powerful. The last line almost confirms this, "I mettled in things man must leave alone." Again, a social comment about realizing the reasons for limiting our "ghoulish" experiments and the effects they may have on ourselves and others. The thought is provoking, but I was not horrified. I just enjoyed the movie.
