Dramatic events continue in the life of a teenager in his last year at the university. But his relationship with his friends is disintegrating. He decided to bring his friends together for the bachelor's degree. The party was noisy and full of wine and many things, but the joyous side did not exist. After the party ended, relations between him and his friends returned to what they were.
"Joshy" is like a weekend with random friends: fun and familiar, but rarely any deeper than the personalities involved. Don't look for more and you'll be fine.
... Joshy would have succeeded had it felt comfortable enough it its own skin to play out without a third act twist that ultimately derails everything that has been set up.
Joshy is perhaps best viewed as a revision of The Hangover, and several other weekend bromances... all too eager to imitate, if not advertise, the illusory notion that senselessly participating in fraternal rites of passage will lead to happiness.
Ultimately, Joshy claims to be a story in defense of its main character's right to a story all his own, even though the film never steps away from him long enough to make us consider that this was even a palpable threat.
