What is your opinion about horrors films

I'm an amateur of horror films. I watched many horror-movies. I may not say that they all were good. Most of them were trash. I like horror-movies with "deep meening". I guess that movies,where people only scream or run away from monsters are boring and routine. I like zombies very much. I watched all George Romero's zombie-films. Yes,probably,most of them are stupid,but we should watch bad films for comparison with good films. 
Well,I can talk about horror-movies a very long time. That's why I already say my conclusion. Horror-films make our fantasy diverse,but they should be watched only by people,who is ready for them. Otherwise,after watching,people may have problems with their mind.
