I stuck with it, but I can't say I understood the hype. I thought it was okay and quite nicely done, but nothing was surprising. I couldn't work out whether it was supposed to be so predictable or not. Some of that actively irritated me. Or maybe I just like all the same films as the protagonist (and the author).
It did get going a bit half way through. I had a period of getting a bit more into it, but the 'twists' were sign posted a mile off and weren't enjoyable to watch unfold at all. The main one was so obvious it became almost frustrating waiting for the author to reveal it.
And the ending was predictable, melodramatic and daft.
I wouldn't recommend it. Shame as there were some nice ideas in it.
