The first episode was a complete mess if it was supposed to set up the next five episodes it missed by a mile. This would be a one star if it wasn't for John Kaczynski who I think is one of the best Jack Ryan portrayals in the Tom Clancy film history. I was a big fan of season one I thought season two went off the rails I didn't understand how they just had Kathy disappear, so many plot holes, poor twists, bad casting. The last season was excellent from a plotting standpoint there were some holes but overall I thought it ended strongly. But if the first episode is any indicator for how this story arc is going to proceed I'm very concerned for season 4.. Conceptually I love the idea of trying to clean up the CIA but we all know that's impossible. I like that Greer is back in the overall Cast is actually pretty strong it's just some of the performances are lacking and Michael Peña as Ding Chavez is pretty embarrassing. His performance is so flat and listless I can't believe anybody's mentioning a spin off series for him he just phoned this thing in or he just doesn't have the chops. Michael Pena does not exude CIA top assassin he's much more likely fitted for a New York City cop at a Dunkin' Donuts. After starting the second episode I almost think you can flush the first episode down the toilet and not miss a thing.
