I did enjoy this quite a bit. A number of things in it put it above the average indie work. The camera work for the most part is quite nice. In some of the over the shoulder conversation shots between Detective Johnson and Claire I thought the framing was a little bit strange. The first time we see over Detective Johnson's shoulder there's a lot of headroom for Claire because she's leaned over. I really enjoyed the steadicam work, it looked quite nice and the crane shot (did you use a crane?) for the first time we see the officer was quite nice.
I felt like the tunnel was AWESOME, but perhaps it lasted a bit too long? Also, the transition from the steadicam in the tunnel to the tripod shot of Claire in the chair felt odd to me.
In regards to the acting, I actually quite enjoyed the performances, especially Detective Johnson. He did quite a good job and was believable. I don't know if you've seen Heroes, but the very first time Detective Johnson spoke he reminded me of the Haitian: "Hello, Claire..."
One other thing, I thought your opening titles were a bit video-ish. They felt very much like you went into After Effects and did a bit of animation and called it good. They weren't bad, per se, but they just felt (to me) a bit amateurish.
I really enjoyed the performances and the story, though I felt like the ending was a bit strange, I couldn't tell if you were going for supernatural or multiple personalities or what. Instead of being left with a "HOLY CRAP THAT FREAKED ME OUT" I was left with "What the heck?"
Anywho, overall, quite a nice work

I look forward to seeing more!
