This series started well with a great cast, but by episode 5 it really bogs down. That episode is completely unnecessary, dealing with side issues and characters that have nothing to do with the main narrative. When it was over, my gf and I had lost interest.
Kelly may have great credentials with directing crime whodunits but his choices for this project were misguided. I suggest he reread the novel, which was awesome, and the movie, which did a great job capturing Thorow's main themes.
