I decided to watch this despite mixed reviews because I love Stanley Tucci. As per usual, Stanley does a great job especially given the writing he had to work with. Tucci and the other death row inmate are fantastic together and it would be a much more interesting show if it was just based on them solving cases. Instead there is a horrible second story involving David Tennant. This is where the show goes off the rails. Tennant's character makes the worst decisions imaginable. I caught myself asking why countless times just during the first episode. It makes the show so unrealistic that it's practically unwatchable. Normally I see Tennant in great roles and I have no idea why he decided to take this part. He does a solid job but his character makes such poor decisions that I don't think any human would make regardless of their level of intelligence that it makes his part of the story very hard to watch. I've seen this in a couple other reviews but if you can throw all reality out the window while watching this, you'll probably enjoy it especially if you're a fan of Tucci or Tennant. If you prefer more realistic writing and decision making by the characters, this might be a hard watch for you. Essentially if you desperately need something to watch, give this a try but there are countless other shows that I would recommend before this one.
