In the supernatural horror film “It Lives Inside” Sam (Megan Suri) is an Indian-American high school student caught between fitting into western culture and honoring the traditions of her Hindu heritage. It’s a key conflict in the film with one side represented by dim and insensitive white kids and the other by Sam’s stern and legalistic mother Poorna (Neeru Bajwa). In that brief description lies both the strengths and weaknesses of this admirable yet unremarkable chiller.

Despite being a little too on the nose in how it’s represented, the above mentioned clash offers writer-director Bishal Dutta an opportunity to explore several compelling themes surrounding cultural identity, assimilation, and faith in our modern society. Unfortunately the movie never goes too deep into anything. But even a light treatment of such interesting and relevant subjects is welcomed. How long that good will lasts may vary.

Growing up, Sam and her childhood best friend Tamira (Mohana Krishnan) were inseparable. But once they entered high school Sam’s desire to make new friends led to them drifting apart. Sam fell in with the popular crowd while Tamira found herself bullied and an outcast. But something else is going on with Tamira. She looks as if she hasn’t slept for days. And she walks around clinging to a mysterious mason jar. A sympathetic teacher named Joyce (Betty Gabriel) encourages Sam to check on her estranged friend.

Meanwhile Sam’s strained relationship with her ultra conservative mother makes things difficult at home. Her more lenient father Inesh (Vik Sahay) tries to play peacemaker but to no avail. Dutta creates an interesting family dynamic and sets the table for some potentially thoughtful developments. But like so much in “It Lives Inside”, the movie barely scratches its thematic surface.

Then you have the movie’s horror element which offers plenty of atmosphere but very little in terms of genuine frights. Not wanting to ruin her newfound popularity, Sam eventually confronts Tamira, breaking her jar and unintentionally unleashing something quite sinister. Tamira suddenly vanishes and the demon begins terrorizing Sam. There’s certainly ambition and some of the symbolism is pretty smart. But the movie never gears up into something even remotely unsettling.

So we end up with a movie that hints at its cultural themes more than digs into them. And we end up with horror that’s too derivative to muster much tension. There are flashes that show Dutta’s potential as a filmmaker and the cast is solid despite the sometimes flimsy material. But as it is, “It Lives Inside” never quite reaches its mark. And that’s a shame because it has plenty of good ingredients that could have made for something tastier. “It Lives Inside” is in theaters now.
