Colleen Hoover's 2016 novel, It Ends With Us, has more than 200,000 ratings on Amazon, averaging 4.5 out of 5 stars.

And the story is now on its way to the big screen. In an Instagram video posted Thursday

Hoover revealed that Blake Lively will play Lily Bloom, a small-town florist,

and Justin Baldoni will play Ryle, the neurosurgeon with whom she falls in love. Baldoni is also directing the film. No release date was given.

Blake Lively, y'all," Hoover says in the video. "She's my dream Lily

Not everyone was as enthused as Hoover.

Blake Lively being cast as Lily Bloom in It Ends With Us is confusing because the character is 23 in the book and blake is 12 years older

like could they not have got someone age appropriate," one person wrote on Twitter

Others seemed to think Lively, who's perhaps best known for her performances on the TV show Gossip Girl and in the 2010 crime drama The Town, was lowering herself to act in the film.
