I wanted a new series to watch, and ended up watching Doctor Who S05E01 as my starting point (as suggested on the Internet, though). In this episode, the Doctor and the alien are speaking about the Attraxi, but I'm not sure whether they are the villains of the season/story.
Compared to other series, such as Arrow and The Flash, or heck, let's take Dragon Ball Z, each season has its own bad guy. And the season is finished when the bad guy is finished, or the goal has been reached. This is unlike Pokémon or Spongebob, for example, where each episode is just a new story around a certain topic with the first episode being equally special and interesting as the last one, and there is no goal or bad guy (well except for the Pokémon League).
Unlike Game of Thrones, though, which does not have a real ending to each ending of a season, but there is a clear continuing storyline going throughout.
My question is: does the final episode of Doctor Who season 5 give an answer to the whole season, does the season contain a story that will be ended/completed at the end of the season?
I'm asking this question because I'm doubtful whether each episode is really connected or just 'random' stories put together.
