It has been so long, I don't even remember. I'm going to guess it was Baby Driver last year (When you're in university, not much time for things like that except maybe on the weekends).
In the cinema it was the greatest showman i think.. on my defense movies here always come late compared to other countries (love simon hasnt been released >:/). At home it was star wars vi! Because of the may 4th marathon!
If we're talking movies that I've only seen once, then I've also seen Avengers: Infinity War just last week or so. I've seen Wonder Woman a few times now.
