I put "Christian film" in quotes because the filmmakers are Christians, but I guarantee it's not the type of movie you're probably thinking of (God's Not Dead, Heaven Is For Real, Kirk Cameron's stuff, etc). It is the first "Christian film" I've seen that wasn't preachy or trying to cram a message down my throat. Messages are there, sure, but they are for you to extrapolate and consider like any good film. Also, the film isn't reserved or afraid of poking at its home audience. In fact, I'd say a good portion of it is designed to intentionally provoke questions in Christians themselves where usually Christian movies are trying to get non-believers to "question" things. Lastly, it is most definitely the funniest Christian movie I've seen (Miles Fisher and Max Adler are superb) and probably the best in terms of the craft of filmmaking (something many others tend to put low on the priority list).
I was just honestly taken aback by how much I enjoyed it. I typically loathe Christian films, having seen so many growing up, but this was like a breath of fresh air. If more Christian films were like this, perhaps they wouldn't be thought of as such a joke by most everyone else.
