On top of having too many plotlines going on, dealing with the drug and human trafficking being perpetrated, there are various personal dramas being portrayed which nearly bring the show to a screeching halt. We're watching one of the baddies' homelife with his wife and child, as well as Greer trying to reconnect with his estranged wife and kids. Also, Cathy (Jack's girlfriend) is back, after inexplicably being MIA for the past two series. So far the scenes with her, whether with Jack or following her own separate plotline have been, well... boring. The writers don't seem to know what to do with her character and I don't believe Cathy and Jack as a couple. The dialogue written for them is awkward, almost stilted. Real couples don't talk like that to each other. I also have a uneasy feeling that they're once again going to make the job she's working on tie in to Jack's case, which was a bit much when it happened in the first series; a second time is ridiculously improbable. For heaven's sake, the woman is a successful doctor, isn't that enough? Why does she- a civilian- have to become involved in CIA missions, too? And though I like Greer's character, watching him have tense dinners with his family and butt heads with his sulky teenage son, several times in the first three episodes, seems a bit repetitive and also predictable: you know from the minute he arrives at his son's football game that he's going to get called away, disappointing and angering the teen once more. And it just takes up more time in an already bloated plot- time which could be better spent elsewhere.
In these first episodes, they also manage to squeeze in Jack's boss Elizabeth's ongoing bid to become head of the CIA, complete with both her and Jack testifying on several occasions before committees in Washington. Boy oh boy, nothing screams excitement like watching committee meetings. These might not even be so bad if, again, the actors weren't let down by their dialogue. But the speeches given by Elizabeth and Jack are just eye-rollingly cliched, meant to show how tough, noble, and righteous they are.
Anyway, those are my thoughts at the halfway mark of the show; there are only six episodes this season. And so much time has been spent setting up so many disparate plotlines that there's no way they're going to be able to tie them all up without rushing and overstuffing the remaining episodes. I'm going to stick it out and finish the show- hopefully it'll improve- but so far it's been pretty disappointing.
