If you're looking for a binge-watch, Netflix reigns supreme.

It’s one of the first – and still one of the best – streaming services out there. There are so many hours of content that you can be sure there will always be something to watch.

But there's one particular area that Netflix is well known for.

The streaming service always kills it when it comes to documentaries... it's well and truly nailed the genre in recent years.

There's now a huge selection of documentaries available at our fingertips.

Whether you're into true-crime or mystery, celebs, fashion or even food, there's truly something for everyone.

The streaming giant has dropped some highly acclaimed factual spectacles.

Like The Keepers for example, which explored the 1969 unsolved murder of nun and school teacher Cathy Cesnik. The documentary filled our growing appetite for true-crime content, arguably spearheaded by Making A Murderer.

Or how about this classic?

The Staircase first aired in 2004, but Netflix picked up the documentary and added some updated episodes last year. It explores the mystery of the death of Kathleen Peterson and is well worth a watch.

And of course, there are options out there for those wanting an inside look into the lives of their favorite celebs.

Lady Gaga's 5 foot 2 gave fans an intimate look at the pop powerhouse behind all the glitz and glamour of the Gaga image she's crafted as she gears up for her 2017 Superbowl performance. It's a candid and honest watch, and fans lapped up the chance to see a different side of the star.

Of course, we couldn't not mention Fyre.

The tell-all doc chronicles the creation of the notorious Fyre Festival from its creation through to its eventual unraveling.

But the newest documentary series to take the reigns is none other than Unsolved Mysteries.

That's right, it's back. The iconic series has returned to give us a new set of harrowing stories about crimes that occurred under very mysteries circumstances.

And boy, did they make an impact.

The show quickly became Netflix's number one most-watched show this week, with all 6 new episodes available world wide.

And people just can't seem to get enough...

I was like this at the end of every episode.

If this wasn't you too, then are you normal?

Thankfully, we have some good news about re-opened cases. Read on to find out which one is receiving a new push to find the killers...

Others had some pretty passionate responses to some of the episodes...

This was one of the most common...

This story was harrowing, to say the least.

Fans were left shocked and borderline nauseous when they found out that Rob, who's wife had been murdered, sleeps with her skull and ashes...

There was something eerie about his story...

And the way he treated Patrice's son. It just didn't sit right with any viewers.

But there was also another story that stood out a lot...

This was such a heartbreaking story. Alonzo Brooks' death came after his friends accidentally left him at a party an hour away from where he lived.

And according to Brooks' family, they suspect his death was a hate crime.

Sixteen years ago, La Cygne in Kansas was a predominantly white area where that very night, 3 black people died in what were ruled as "brawls" in the area. The entire town refused to talk about it or aid the investigation at the time.

But now the investigation by the FBI has re-opened thanks to this series.

Because of the lack of effort by the police and the residents in that time, the investigation has been re-opened and now a $100,000 reward is being offered to anyone that could help lead to an arrest.

FBI Agent Leena Ramana said this:

“It’s been 16 years, but we hope that with this passage of time, someone who has information will come forward," she said. “Some of these kids, who are adults now, may have been scared to come forward before, or may not have known what they saw was important. But any piece of information is significant and could be the missing puzzle piece we need to solve this case."

The cause of death was undetermined at the time, but many believed it was a suicide...

Yet there was no sufficient evidence to support this baseless claim. One other theory suggested he accidentally tumbled into a relatively shallow creek, in Linn County, leaving behind his boots and hat, all with no witnesses whatsoever. It was very hard to believe.

The producers of the show also confirmed some more good news.

Across multiple episodes, witnesses and other "credible" sources have come forward to help investigations move one step closer and you never know, these "unsolved mysteries" might just be solved.
