When I was a kid it was Faces of Death , then I saw real death in real life and then hated the Faces of Death series.
Now it changes every few years and is Sci-Fi and/or mind bending movies with really good plots.
At my core the movies below seem a part of me most
Orlando
HACKERS ~ life changing
Silence of the Lambs
Gothic
Nightbreed
Beaches ~ after I moved to LA
Halloween ~ life changing
