Imaginary Friend

I knew going in this was a Lifetime movie and set my expectations accordingly, then was pleasantly surprised by how intense it became. It starts out with a slow burn then ramps up and doesn't let go until the very end. That's where it lost me, though, that terribly explained ending that didn't tie up all the loose ends. Thinking I may have missed something, I looked for online reviews of this movie and didn't find anything helpful. It jumps from the climax to a wind down scene, a just-deserts scene, and then a final scene. The problem is the climax doesn't resolve and forcing a scene change where they did is a cheat because there was no good way for the heroine to get out of the situation. I know I'm being a little vague, that's because I don't want to give anything away. It's frustrating though because everything up to that point was done so well, but that ending... No thriller should leave you with unanswered questions.
