Every single character is a stereotype with no personality and no chemistry. You have the awkward and unloved lead, his aggressive boss, the manic pixie dream girl with the overly aggressive black friend, the country girl with the country accent, the overtly sexual kinkster in a punk band, and the list goes on. None of these characters have ANY chemistry and it makes every single interaction painful to watch.
Every piece of dialogue is a fumble that completely misses the mark it's aiming for. Scenes that aim to be funny are stifled by the fact that none of these characters fit together. Even scenes that are meant to be heartwarming or dramatic feel over-acted. The dialogue isn't funny or interesting, it's just deeply awkward.
There is nothing redeemable about this movie and if you are someone who experiences secondhand embarassment, you should avoid it. Save your money and watch something else.
