Yes thank you, that's what I have tried to explain to so many people. It's all about intent.

I love your use of Shutter Island as an exemple of a movie that tried too hard to be smart and mindbinding (even though I am usually a Scorsese fanboy). I felt a similar way about Inception. In comparison, Coherence surpassed both those movies in that regard with a budget of only 50k$.

However, in a completely different line, I loved John Wick because it was just about a guy going all berzerk at people that killed his dog. It was not trying to do anything else than being about people shooting at each other, but it was directed so well that I was hooked from the get-go.
