It was supposed to a romantic comedy, but it wasn't funny according to me. If the author thought that the pranks between Willa and Landon was supposed to the comedy then I don't know what to say.
I have to say Willa here seems to be enabling her dad to drink. Always picking him up, from either the police station or Vegas, cleaning his trailer, working 2 jobs which then becomes 3 jobs and that one job was to pay for her dad's debt (in the end it was a lie). She did demand her dad to stop drinking at the end, it was after she went to pick her dad up in Vegas after he gambled his car away, and after she had to play poker with her body as a collateral. Good thing she wins.
I also didn't get her fight with Jameson, I know she called Jameson Mr. Drake when her friend Maisie picked her up in the garage because she was scared of what her friend thinks about her. In my opinion, it wasn't very big of a problem, but it was made big.
