The Half of It is solid.
Yeah, it's not perfect but it takes a trope that has become repetitive over the years and puts its own spin on it. I'm talking about that trope where a person who's probably popular likes someone, but has nothing in common with them or is just plain dumb, and so they have to ask the less popular character for help... and the plot usually progresses in the same way too; the love interest realizes that the popular character is not who they have been falling for all along and then chooses the less popular one in the end. It's pretty basic stuff that has been seen over and over and over again. And movies have tried to take a spin on it before; Sierra Burgess Is A Loser being one of the latests examples. But while Sierra Burgess failed, The Half of It succeeds at making that spin compelling, insightful and just straight up wholesome.
Honestly it's a very difficult trope to fix, especially with the changing times, a lot of people are sick of the manipulation that can take place in these types of stories, not to mention the lying and scheming. And what I think The Half of It gets right is the understanding that what can make or break this trope are the characters, their dynamics and their motivations.
And oh my goodness the two main characters in this movie are a delight. Yeah they make mistakes, but it's usually never out of a place of malice or selfishness. And I believe that the development of their friendship is what makes this story worth watching.
This is not just a cliché teen romance. It's a movie that tries its best to capture the essence of being a teenager navigating friendship, love and life in general; and honestly, I think it does a pretty good job at it.
