I have mixed feelings about this movie. Though some parts were enjoyable, some others were confusing. Here's what I liked:
-The soundtrack
-The performances
-The middle part
-The family dynamics and their relationship development
-The relationship between the boy and his friend's sister
Now, what I didn't like:
-The open ending
-They didn't explore his relationship with his friend more in depth
-The character just accepted everything that happened to him
-There were some plot holes and things that weren't properly explained, like the girl's past
-The movie tried to be funny in some scenes and that was a bit awkward
So, 5 out of 10.
