The Sisters (2004)

Our film opens with a back story, and we've several young persons laid over between gigs. We've scenes of truly horrific nature, likely prior to our characters' appearance. They've a prankster amidst them, and it appears as if things are getting rather spooky beyond their understanding.
As the supernatural occurrences begin, we've a terrible tragedy within our group of young characters, followed by yet another tragedy. I'm enjoying the practical effects over the ridiculous use of cgi nowadays, and it's so much more fun and requires our actors to perform.
The cinematography is very 70s with its primarily muted colors, except when it's needed to show moments of vibrancy. So it seems our backstory of the original tragedy is far more complicated our maybe much darker and simpler than it first appeared.
