Negative Positive
Title: Effective for me.
Review: Watching it, without hindsight prior to waching, and little interest now after watching it, I never understood what was going on. Fortunately not important for me. I watch the acting, register the visual effect (butterfly or not). And the three kids, at 7, and 13, did it for me. The violent kid, above all. What a performance! And that's what my stars are for.
