This review may contain spoilers. I can handle the truth.
I can see why Denzel chose to direct this - just to cast himself as the lead. He never shuts up. The camera never stops moving really. He never shuts up but his acting is quite good in a Denzel Washington kind of way (except for when he can't taste anything and keeps telling the air about while licking a baseball bat). Viola Davis is great though.
Best part was when he died...although that did seem to take forever.
