Alright, B movies. Labeled as such because of the typically lower budget, poorer acting and campier story lines.
For a lot of people this is a turn off to the movie, however it may in fact be their saving grace as well. Because in the end no matter how serious a B movie is supposed to be, they can all become comedies.
And it is exactly what makes them less valuable that makes them priceless. Now it usually helps to have a drink or two in your system when going to watch one of the said movies because it can increase the appreciation of the humor. The humor found in ridiculousness.
The combination of bad special effects, bad acting, bad story can eventually cross a threshold. The corniness takes on a new level, and it is hilarious. Take the movie Killer Klowns from Outer Space. Its about an alien species that lands on earth to abduct humans. The aliens of course look like clowns and there spaceship is shaped like a circus tent. The humans they abduct are wrapped in cotton candy and suck their blood through crazy straws. The whole concept of this movie is outrageous. Did they really intend for it to be scary? Because if they were they failed (I can't imagine that was their intent, look at the tagline), but made a great comedy.
I feel horror movies, action movies, and science fiction tend to make the best B-movie. Maybe that is just because those are the types of movies I tend to watch. Thinking about it, there might be some really bad good romance movies. Let me know if there are any.
It does take a certain sense of humor to appreciate a "good" B-movie. The kind of sense of humor that makes you laugh at jokes that aren't funny, because they are so bad that they are funny.
Take this for example:
A string walks into a bar, goes up to the counter and orders and drink. The Bartender turns to the string and says,"Go away. We don't serve strings here." So the string walks outside for a moment, when an idea hits him. He ties himself up and frays out his ends. He goes back into the bar and again orders a drink. The bartender looks at him and says, "Aren't you the string that I just didn't serve?" The string replies "Nope, I'm a frayed knot!"
Now if you laughed at that, you should go get a six pack, and find a "good" B movie. Check out http://www.badmovies.org/, a site I am not affiliated with, but it is a wonderful reference (look for the sci-fi movie with David Hasselhoff).
So this is a situation of bad equals good. Which leads to one of the best parts of B-movies, they are cheap. A friend of mine who is big into B-movies just bought eight movies for eight dollars.
They are great, they are cheap, and fun to watch with friends. And that is why B-movies kick ass.
