The point of this movie is to make you laugh. Allow you to have a little bit of fun as it pokes fun at Millennials in a harmless way.
Comedy is subjective and not everything in this movie lands for me. But that might be different everyone. And they also obviously don't have all the resources to make it as fancy and perfect as some big-budget Hollywood blockbuster. But for what it is as a small indie comedy, it's effective and harmless with a strong core of acting. Some of the side characters are annoying, but the lead male and both lead females do a great job.
Every movie is someone's life work and more people, especially people on this site, need to do a better job at respecting the filmmaking process. This particular movie took six years to make and had a lot of effort go into from someone who has a life, a full-time job, and family to feed and take care of, but still wanted to make time to follow a dream. Even if you don't like the final outcome, and I agree that not everything works for me either, the least you can do is have some respect and not casually throw out your 1/10 after giving it two seconds of thought or only watching the trailer.
It's hard to make a movie. And this one is totally fine. Give it a chance!
