As soon as Netflix started creating their own original content, that content started winning awards up to and including Emmys.
House of Cards, Orange is the New Black, Daredevil, Unbreakable Kimmy Schmidt, and more are contributing to an exclusive line-up that is arguably of a higher than average quality than can currently be found on network television.
When watching a series, the next episode auto-starts after one ends. You can navigate back and forth through episodes and seasons without having to exit to the show page.
If the show you're watching isn't a Netflix original, then you'll probably have to wait for the next season to begin before the last season becomes available. E.g., Season 2 will be available on Netflix when Season 3 starts.
