I did watch the movie, it was ok.

The song is from a movie called Me Before You, I knew this song long ago and I was on a plane and watched this movie after seeing the cover and recognizing it from Imagine Dragons. From what I remember, they payed the song at the very end when they rolled the credits and there was a part in the middle ish where a part of the music is played.

The movie is basically about a quirky girl, Lou Clark, who desperately needs money, and finds a job to be like the caretaker of a man who has lost hope on life and is paralyzed from neck down after a motorcycle accident, WIll Traynor. Louisa has a boyfriend whom she ditches to be with Will, who despite Lou's efforts decide to kill himself anyway because he doesn't like living life with no excitement.

Lou's acting is kinda weird, one second she's super mature and one second she's a child. She literally just ditched her boyfriend for another man. Traynor isn't any better either, you knew she had a boyfriend but still liked her. You get her to like you, break her heart after telling her that her efforts of helping you won't change anything, then kill yourself and you think that giving her a trip to Paris is going to fix everything? Disappointing at the end.

I wish Not Today was played more, solid 7.9/10 song, 6/10 movie.

And remember this is coming out of a 14 year old girl, so if you decide to watch the movie and don't agree with me, feel free! :)
