Star Trek movies (Original)
The first one is my sentimental favorite - partly because it was such a huge deal when they actually made a Star Trek movie, and partly because the first time I went to see it, I was loaded on shrooms. It was an absolutely amazing experience.
Unfortunately, the day was kind of spoiled because after the movie, we accidentally urinated on some poor drunk who was passed out in a parking lot. It wasn't really our fault - he'd covered himself up with some old rags and newspapers behind a dumpster, and we thought it was just a pile of garbage - but still, we felt pretty badly about it. But the movie itself was extraordinary.
