Not that anyone cares, but..
This movie has special meaning to me. I'm only in my 20's, but I always loved the 50's aesthetic, the clothes, etc. What I loved about this movie was essentially the "second chance" setup. Many movies have approached it in such a way that didn't quite hit the mark for me. This did. Although as some others said, I do feel Turner did look unbelievable as a teenager (literally), I loved her performance. Particularly the scene in which she goes home again for the first time. The look of wonder on her face when she sees her mother.
This movie hits a personal chord with me because I (as many others probably do as well) wish I could have a second chance too. I no longer have my family (my mother and grandparents raised me.), they all died when I was 19 and the family home was sold. I married a putz and now am waiting for the divorce to be finalized. I grew up incredibly fast.
If those second chances were only real, imagine the paths our lives could've taken.
Anyway, to anyone that read this, thanks. Just my personal little sentiment about the movie.
