Part 2 is my favorite. It was my most anticipated film when it was released but I didn't see it until later that year on a double bill with the first film.
Although I saw and loved Friday #1 on Showtime, the theatrical print was so much more vibrant than the cable version in my eyes. Our tiny TV made all the blood look black.
When Part 2 came on, the theater was near capacity. I remember that final shock really getting the audience good. The cat and mouse chase between Ginny and Jason in the damp, drizzly forest is also one of the best ever filmed.
