As most television shows are on a hiatus at this time of the year, you can keep yourself entertained by binge-watching old seasons of popular series that you have missed.

Here's a list of the top ten shows that you need to watch before they return with their latest season:

The Walking Dead (Season 6 returns on 11 October, 2015)

This show definitely needs no introduction. The series, which promises a lot of zombie action, is based on a series of graphic novels of the same name. "The Walking Dead", which has broken numerous records, follows the story of Sheriff's Deputy Rick Grimes, who awakens from a months-long coma to confront a new, apocalyptic world overrun by zombies. If you still haven't watched it, then you have got a lot to catch up on.

Fargo (Season 2 returns October 2015)

A black comedy crime drama, Fargo is inspired by a 1996 film of the same name by Coen brothers. Starring Martin Freeman and Billy Bob Thornton, the show is about a drifter named Lorne Malvo, who arrives at Minnesota and influences the population with his malice and violence, including insurance salesman Lester Nygaard.

Doctor Who (Season 9 returns September 2015)

With the revival of the Doctor over the season, you don't really need to catch up on old seasons. But if you wish to do so, you can watch the classic series of around 26 seasons or simply watch last year's, where Peter Capaldi makes his debut in Season 8 as the 12th Doctor. "Doctor Who" is a British science-fiction television programme by the BBC (from 1963 till now). The programme narrates the adventures of the Doctor, a Time Lord who is a space and time-travelling humanoid alien.

But, he returns five years later as a changed man, determined to clean up the city as a hooded vigilante armed with a bow.

The Flash (Season 2 returns on 6 October, 2015)

Based on the DC Comics character Barry Allen/Flash, the costumed superhero with the power to move at superhuman speed, "the Flash" is a spin-off of "Arrow".

We can never get enough of The Simpsons, can we? The most popular animated show will come back with its 27th season this year and is still going strong. While the show has received mixed response in the last few seasons, we still feel it deserves to be watched.
