To paraphrase Game of Thrones' doomed nobleman Ned Stark: brace yourself, reality TV is coming.

From this week Biggest Loser is back, this time taking on the weight problems of an entire town, and it's only days before The Block and My Kitchen Rules pop up again.

The newest crop of singers for The Voice are in studios right now giving their all, the next housemates for Big Brother are being chosen - and every other dancer, singer, juggler, chef across the genre is getting ready to go.

And our screens are, as usual, about to be covered in it. The reasons for that are many. Not least because it's often an inexpensive alternative for the networks.

But primarily it's because they're incredibly popular, with the reality formats regularly breaking the magic 2 million viewer mark last year.

As maligned as the genre is, and there's no shortage of people willing to say how much they hate the reality world, there's ample evidence that at least some of those who say they won't watch reality TV are doing just that. And probably a lot more than just some.

And why not? Reality - even when it's just a gaggle of hipsters sitting around a pool arguing - does have a place on the television landscape. And not just because it's cheap.

The reality shows, even when re-edited or produced to give us stereotypes, often show us more about Australia than any ''quality'' drama or comedy can.

The opinions expressed in the heat of a kitchen, or while someone is exhausted after a day's training, are often more honest than anything seen anywhere else.

These are ordinary Australians and as cliched as the phrase has become since the promoters of Big Brother claimed it more than a decade ago, this social experiment can be valuable.

And if nothing else, the pleasure of eating dinner while the Loser contestants sit down to a lettuce leaf cannot be overestimated. Enjoy!
