Re: TV SHOW discussion thread (NO FUCKING SPOILERS please)
I watched season 1. Your man from veronica mars appears, turns out to be this big bad guy, disappears for about 6 episodes, reappears to tell jim caviezel he is back at the end of an episode and then disappears for another 6 episodes.
Amy Ackers arc only lasted 3 episodes as well.
Those flashbacks add nothing from what I saw and there wasn't any real over-arcing story and 90% of it is pure fluff of jim saving some random.
It might not be like other shows in the way their story arc's tend to happen, but in the context of Person of Interest it does develop it's story-lines, I get what you're saying, but it's not the kind of show to have 2 seasons completely attached to a certain character.
