In defense of Communion
(Fair warning: This will be a long post, and I don't suspect the mockers of this film (who are probably just young immature guys) to read much of it because reading it requires actual intelligence, patience, and having an open-mind to someone's opinions that differ then you're own.)
I feel bad for Walken. Too many people don't take him seriously anymore. He's one of the greatest actors in the world, yet a lot of fans (mostly young male morons) want to turn every one of his performances as a joke, and make fun of him and/or just not take his work seriously. (BTW: I'm a 26-year old man with a great sense of humor, but I know when to pick my spots unlike others.)
Communion is a wonderful film, and one of the scariest movies ever made. To cover up some people's fears, they want to mock this movie, the idea of aliens, and anyone who claims to have had contact with them, and the fact that Walken is in this movie only increases these immature young men's drive to turn every role Walken does as a comedy. Then they wanna point out the lack of the special effects. It was the 80's. You spoiled brats who are use to CGI need to understand that, and there are more to movies then special effects, like good acting, and a great story, and Communion has that, but your immature way of thinking blinds you to that.
People fear what they don't understand, and that fear soon grows to hate, and some people express their hate differently. Most young men just wanna smirk, and make bad jokes, and mock what they fear.
Aliens are the most realistic "monsters" in the horror world, and everyone knows that. Any one of us could be a victim to alien abduction. That is where the discomfort of it all comes in, and for anyone to think we humans are the only living creatures in this giant universe is just plan egotistic, but it wouldn't surprise me that the haters/mockers of this movie would be too cocky to know that.
