Scream
I used to be so scared of horror films, i've used to barely watch any cause only the idea of watching an horror film used to make me shit my pants. I used to love the "scary movie" films in middle school tho, they were so funny and i always knew they were the parody of some horror films and i've always thought that i wanted to see the original ones some day. One day when i was 14 or 15 i finally convinced myself to watch one, this one. Thank god i finally convinced myself, i loved every second of it and realized that this is my favorite genre, it can be considered as a sort of core memory because from that moment i started watching much more horror!
It will always have a special place in my heart.
