The movie is very unclear on its rules of how the time skipping works. As far i i could figure out, it is similar to the "click" movie without the main character trying to figure out what is happening. She just wonders around aimlessly enough though she is losing all this time. There is a hint that the journal given to her at the beginning has some sort of power but she never really uses it during the movie. It seems to be just a normal journal that she writes in during the year. I would think that after the second or time, she would consult the journal rather than walk into awkward situations.

There is a theme that she is not treating time seriously so she does not deserve the extra time however after she changes, it does not stop or chage the process. In the end, the time jumping just stop for no reason.

Definitely a unthought out idea. Should have worked longer on rhe script.
