Of course it is predictable. It is a rom com. I really liked the actors, particularly when being funny rather than ernest. Yeah, the plot point that he got published (not a spoiler, is point of the movie) despite being a boring book doesn't work. Publishers wouldn't publish this nonsense. And storyline could have been more engaging, but overall, it made me smile, and I enjoyed it. I liked the music too. Closeups of actors were a little too close.
