That is of course, if the producers are even planning that. They could very well end the story with this season and fans wouldn’t mind as long as it concludes in a good way, and there are lots of possibilities to make this happen in any case.
But it wouldn’t be a very sensible move, as the current state of “House of Cards” is a very successful one, and the show still has a lot of potential if it’s developed well enough.
And Netflix certainly know their audience well enough to realize that people want to see even more of Frank Underwood and his shady dealings. The character has become a fan favorite in record time, despite having lots of flaws and displaying an overall unfriendly attitude.
It’s an interesting case of a show that manages to bring out positive sides in characters that shouldn’t really have them, and many people have been praising the producers for managing to combine their different plot elements in such a creative way. Frank Underwood could have something even more interesting coming up for his character soon, and we’ll see how things go once season 4 airs. Which, at this rate, is going to be in at least a few months.
