Deadpool
I still love the hype from back then. From the leaked test footage to the first trailer, I was completely hooked and told everyone about it. I remember exactly how I snuck into the cinema when I was 15 – and it was 100% worth it.
Deadpool 1 was a massive catalyst for the superhero genre and had a noticeable impact on film history. The film showed that R-rated comic book movies with adult themes work and don't have to be watered down. After that, the genre visibly became more daring. Add to that the extremely comic-accurate suit and mask, which conveys emotions despite being fully covered.
An absolute milestone.
