If you read the few reviews on here that bashed the movie, you will believe it was pointless. They missed it entirely. I can only say that this was a very enjoyable tale start to end, and well worth watching particularly for anyone who enjoys a slow build to a finale. I am always looking for an original story and original telling of it, and highly recommend this nice little gem that you will not regret seeing.
Don McKay is a suspense crime thriller that you will want to watch a second time because the reveal at the end makes you re-examine the entire movie. I give this 8 out 10 stars because the movie did get a little bit into the unbelievable realm when the puzzle started to unravel, but the final payoff is so filled with revelation that you forgive that.
The first half of the movie was paced and shown in a very similar style to Shutter Island, and I felt was extremely well done. (However, if you don't like a slow build and pacing that takes it's time, then you probably won't like this movie.) I personally started to believe that this little movie could have gone for a major ending of epic proportions -- it was that well done in my opinion. But, Act Two did keep the movie on a smaller scale and got a bit quirky in parts, which was a disappointment. However, it was all worth it as you finally understand what was going on the entire time in the final minutes. It keeps you guessing the entire time, and even when you do guess right, which I had done, the ending still took it to a whole new level that I did not expect. Total surprise.
I will also add that I was laughing out loud during several sequences of the movie. The dark humor was really good.
Acting was excellent, although I say that after understanding the whole situation at the end. During the movie I felt it was more like average, but that ending puts it all in a new light.
Cinematography, score, and sets were excellent, felt just right for the tone and added a nice reinforcing effect on the movie.
