After so many months of putting it off, I sat and watched the entire film. And yes, I agree with my original analysis.
Every film has some ounce of likable substance or style.
Mommy was unintentionally funny. The first two minutes of this film is entirely riveting. The style used is great with an enchanting musical score to accompany it. But that's all folks. Everything else is the worst crap I have ever witnessed put on screen.
