I am forever a sucker for movies set in the wide open expanse of the American west. This penchant is what sucked me into seeing the low budget dramatic thriller "Big Sky".

Now admittedly I don't know what severe agoraphobia looks like. But I imagine that Bella Thorne does a pretty damn good job of depicting how this insidious psychological affliction debilitates and paralyzes those who can not bear interaction with the outside world. And Kyra Sedgwick as her less-than-model yet loving mom and the consummate acting pro is first-rate despite being rendered incapacitated early on in the proceedings. There's your propers, kids. The rest of "Big Sky" is so implausible, inexplicable or just downright impossible it loses it's way pretty quickly, never to regain any true traction.

Make it a big whiff on "Big Sky".

Hazel (Bella Thorne) suffers from debilitating agoraphobia. Her mother Dee (Kyra Sedgwick) takes her to a desert treatment center. She is transported in a box inside a van along with other passengers. Suddenly, the van is attacked by sibling bandits and a girl is kidnapped. In order to save her dying mother, Hazel faces her fears to find help.

Not enough happens to make this thrilling. The characters are split up. They set up something but more needs to be done with it. It climaxes with a convoluted Mexican standoff. Much of it is unreasonable but mostly, it lacks tension or thrills.
