It's fairly obvious that the inspiration for Secrets In The Snow is taken from The Breakfast Club. However John Hughes never put in the religious overtones in any of his films. I doubt that any of these characters would have been seen in any of his works. But as this is a Christian movie there are parameters.
Not as edgy as the Breakfast Club because we sure don't have a tough guy like Judd Nelson or one thinking of suicide like Anthony Michael Hall. But these are all small town kids stuck in their high school with one of their teachers, they're not in detention for any rules infraction. Just a nice blizzard and with lots of time to spare they tell each other's secrets and bond somewhat.
The most interesting characters are Hollie Shay, the glamorous teen queen of the school who dresses to kill and is a fashion role model. But she's facing some tough economic times ahead and may not have the attitude to deal with it.
The other is Vincent Seidle who is the local rich kid who gets a lot of rich kid toys, but he feels no real love.
They're all not bad kids and the climax is a church service attended by all. In their little white bread world there sure is no diversity. Makes it all unreal.
Still the religion is there, but you're not hit with it with a sledgehammer. I doubt Secrets In The Snow will go beyond Christian audiences.
