Not so much asking what was the first monster/horror film you saw, though it might be the same answer but what movie hooked you? What got you to go to the drive thru, watch Creature Feature, collect FM, (or VHS and Fangoria or DVD depending on your age).
For me it was borrowing Frankenstein and Dracula from the library when we got a VCR in 1987. I had heard about these movies, but this was my first actual experience watching them, and it hooked me for a long time.
