TV shows are like boxing matches, you have the main events like Breaking Bad, Boardwalk, Game of Thrones. Then you have the undercard or as I say fillers, and this is definitely on the filler list.
I'm watching this in the UK and like this show while there's basically naff all on currently. I'm really not sure the reviewer's have been watching the same show but it's all about opinions and there's counts just like mine does I hope.
It may well be a one season wonder in the end, but currently there's a lot going on like political gamesmanship, murder, blackmail and a reasonable storyline to keep me interested. As said I do class this as an undercard type show, but it's watchable and doesn't deserve the reviews it's been getting.
Personally a lot of shows that I've watched in this class have been canned by the TV powers that be. Which begs the question, do my great American cousins actually know what there watching sometimes, when shows like Grey's (bailed after Season 5, The Mentalist bailed and a few more I dare not mention) are still out there going strong.
I love the US drama, best TV on the planet. They're very few UK shows of equal and we have a tradition in the UK of only having 6 episode seasons, less if you think of Luther.
This is a new golden age with so many great US shows, 3 I've already mentioned, alas BB is no more (nothing touches that). I'm enjoying Hostages, just like The Blacklist, Revolution, Under The Dome and Continuum. All enjoyable filler shows to watch while the main events are on break.
If you've given up on this, I'd encourage you to go back to it while there's nothing on.
