The Signal (2014)

Three college friends (Nic, Haley, and Jonah) are traveling cross-country to help Haley relocate. Along the way, they discover that a hacker who compromised some of their work at MIT is nearby, so they take a detour to confront him. I was enjoying this story: it was one about an imminent break-up, a kid trying to figure out how to navigate his life in the wake of a recent diagnosis affecting his legs, and the excitement of an encounter with a hidden foe.

But then this turns into some other movie. Nic wakes up in a bare-bones medical facility and is being handled by people in HAZMAT suits. Haley's in a coma, and -- though Jonah is supposedly not in the facility -- Nic is able to communicate with him through the vents. And there's something weird going on with his legs.

I wound up pretty frustrated and in need of an explanation.
