Finally finishing up Person of Interest... real shame that got cancelled.. mind you my personal opinion is it died for 2 reasons: 1. When launched, no one knew about the NSA and everyone thought it was science fiction... now we know it is true and it hits too close to home. Imagine someone who has survived cancer having to watch "The Fault in our Stars" 2. The American necessity of making 20 or more episodes. Most of the great arcs of the show were 8 or 10 episode arcs at most... stretching it to 20+ really added a lot of fluff that bogged it down.
