First things first: this is a cancelled show that ends on a cliffhanger. So there is little sense in watching it when it comes to closure. There is none. And I can understand why.
It is not totally awful, the action scenes, in particular the fights, are done well. But I can't shake the feeling that they are there just for the sake of it and the plot is often just a bridge towards the next fight.
The story is not very original, it takes the usual building blocks and arrange them, well, not even new. And it is too transparent. The surprises and twists are cabled in advance.
Too many storylines. It started well but we follow all those characters around and you wonder if there is a connection outside of the programm. I'll admit this could have been adressed in later seasons.

As I said there is really no need to watch this. You can't even take that ending and let your mind fill out the rest. They clearly did not expect to be cancelled. I only watched it because I wanted to know if it would have been worth watching had it continued. And from my point of view that would be a "No".

On a side note: I did not watch any of the Bourne movies and I don't think you need to to follow this. It works fine on it's own.
