To be honest, I believe its title to be its failure. Like the writers and producers just went along with it after script editing without rechecking its connections.
M.D. Vigilante or something that would bring it the show's class would have been better. Complications for one would be too complicated to search in Google as it is a common word not only in general but medical terms as well. It's flair would have been lost to the fray.
On the show, I believe the first season was setting up John to be a continuous vigilante throughout the series and getting better and more determined at it, flowing his PTS syndrome into a more less symptomatic more driven goal that would flourish into a probable "Prison Break" like or otherwise "The Company/E Corp" face off i.e. International Cooperation/Multi-conglomerate Company.
So to be hard driven into this situation and molded by the plot in the first season to me was a very good start. For first seasons, I'm rather withdrawn with how the cast plays their characters because I believe most things in life are work of progress so it would not be a surprise if they seem too dry at this point. There was no plot to submerge them into a character that would be growing yet.
As with many first seasons, most things revolve around the main repeating casts and the play with Gretchen and john was masterwork for a first season. I especially love that they added scenes in John's psychology where he back and forth himself towards explaining what the entire first season was about, "Killing the cancer's source". The ideals presented in this form was admirable.
It is just that I would remain with this remark until if season 2 was also dry with each of the character they have ensemble into the web around John. So I say give it a shot for Season 2 because Season 1 did keep me wanting for more, not sort of like GoT or other high production types but because of its "Hannibal" like appeal of character interchange of abstract moral ideals.
