Blake Lively was the wrong choice for the Lily Bloom character. The young Lily is much better of an actor than Blake is in my opinion.
Baldoni on the other hand, his acting is phenominal, he was the PERFECT choice for his character, and he's such a great actor. I legit got scared when the first scene of abuse showed, like I jumped in my chair! That shows you how good of an actor he can be.
Baldoni, the young Lily, and Atlas are the best things about this movie (not the violence of course, just the actors.)
I don't really recommend this with that being said, It's an okay-ish movie. It's literally all about Blake, even the advertising is all about her.
