Person of Interest is a relentlessly silly show, although you wouldn't necessarily pick up on it at first. It leans into it more with each season until that's all there is. I still enjoyed it, it is pretty self aware. I would not watch it with the idea that it has any relevance to anything.

That's how most good shows used to be. Start serious, maybe a bit goofy, then by the end everything has gone way off the rails.

Almost like you were watching the show from the eyes of the machine?
