My Definition Of "B-Movie"

Low budget movies (B-Movies) are movies made with almost nothing. They are normally Sci-Fi or Horror movies and their "Golden Age" were the 50's. While watching B-Movies you can always tell that the spaceships, monsters and stuff like that, are fake. A lot of people hate B-Movies because they are cheap-looking and sometimes boring, but I personally think that they are very creative in the use of special effects (like in Harryhausen films) and I always feel that this movies are innocent and charming.

For me, there are four types of B-Movies:

1. The G.G.G. B-Movies (Great story, great characters and great special effects) 
2. The "Wannabe" B-Movies (Great Story, Bad Characters and Bad special effects)
3. The Underground B-Movies (So Bad They're Good)
4. The Z- Movies (So Bad They're Bad)

My favorite types of B-Movies are "The G.G.G" and "The Underground".

Here some examples of B- Movies:

G.G.G B-Movie -'Invasion Of The Body Snatchers'

Wannabe B-Movie -'Phantom From Space'

Underground B-Movie -'Killers From Space'

Z-Movie -'The Screaming Skull'
