Inner Demons is a 2014 American found footage horror feature film directed by Seth Grossman and starring Lara Vosburgh, Morgan McClellan, and Kate Whitney.
Inner Demons follows an ‘Intervention’-style reality show crew that films an episode about a sixteen-year old girl, a former A-student, who is fighting addiction but may in fact be suffering from something even more destructive: demonic possession.
The movie is an inquiry into the truth about her – with symptoms that straddle the disturbing and scary intersection between insanity, addiction and true possession…
“While the concept may be a little lackluster, the efforts of Vosburgh unite with a booming ending to make Grossman’s rehabilitation haunter worth a trip down the rabbit hole.” We Got This Covered
” …it’s pretty tame for a sub-genre that relies largely on shock factor. Then, in the final 10 minutes or so, it’s as if the filmmakers realized they had to kick it up a notch, and it turns into a virtual blood bath. It’s a much-needed jolt of edge and energy that turns an average demonic possession movie into… an average demonic possession movie with a good ending.” About.com
“Grossman generates almost no suspense, save for one or two of those static surveillance shots, since we know almost right from the beginning that Carson is under a demonic influence. How do we know? Among other things, the camera image becomes unstable. Shocking!” Den of Geek
