Banshee Chapter didn't really do it for me unfortunately, there's some intriguing ideas at play here but the film didnt hit enough of the right beats to be a memorable horror.
The premise is basic but enticing - a drug developed by a shadowy part of the US government has some pretty alarming side effects. A good friend of our heroine, Anne, goes missing after taking the drug, then his camera carrying buddy who filmed him taking the drug also vanishes. Anne decides to investigate further with the help/hindrance of a Hunter S Thompson style novelist (played by Ted Levine).
I wont say much more about the plot but it all gets a bit strange from there. The opening scene is a cracker but I didn't think the film built enough real tension from then on. There's a few jumps along the way but these are mainly from the usual tool of dark quiet scenes being interrupted by sudden loud noises or the sudden appearance of characters from the gloom.
The films had an awful lot of praise so maybe its just me, it wouldn't be the first time. I came away disappointed though.
