This is a very pretentious film full of (not only) goth clichés. The characters are poorly written, acting is hillariusly bad most of the time and the plot - despite its pretty standard coming-of-age formula - feels more like a series of events/scenes that together don't form anything coherent or atmospheric. Atmosphere and pacing are also nonexistent.
If you're edgy teenager at the start of "goth/emo phase", you might perhaps enjoy this film. Otherwise, I don't think so...
As for the goth subculture, it's portrayed in the most stereotypical and cheesy way possible (dancing at graveyard, suicidal talks, "Bela Lugosi's Dead", death jokes). I definitely don't recommend this film to anyone who wants to seriously understand goths and their culture.
At least Joey's grandparents were kind of funny and the ending was somewhat sweet (nevertheless, still very cringy).
