There have been a slew of films tackling best friendship as a core relationship in ones life, and how a big change can test its strength. Babes did this exceptionally well, mixing genuine comedy with a heartfelt storyline. Adult Best Friends lives in that same category, following Katie (Katie Corwin, who co-wrote the script) and best friend Delaney (Delaney Buffett, who co-wrote and directed the film) as they navigate Katies engagement to John (the Scream franchises Mason Gooding) and what that means for their friendship moving forward.
