Netflix viewers spot huge mistake in Menendez brothers series that ruins 'everything'

Eagle-eyed Netflix viewers claim to have spotted a big mistake while watching Monsters: The Lyle and Erik Menendez Story.

There is one series that everyone seems to be watching on Netflix right now and that is, of course, Monsters: The Lyle and Erik Menendez Story.

Following on from Monster: The Jeffrey Dahmer Story, the second season instead focuses on the case of the Menendez Brothers, Lyle and Erik.

In 1989, the brothers were convicted of murdering their parents at their family home in Beverly Hills, Los Angeles.

45-year-old José, and his 47-year-old wife Kitty Menendez were shot 16 times at point blank range with shotguns.

Following this, the brothers then called the emergency services before later admitting to the murder following their arrest.

During their trial, they alleged that they'd suffered physical, emotional and sexual abuse at the hands of their parents, however, prosecutors argued that they had killed them for financial benefit.

Lyle and Erik were found guilty by a jury and sentenced to life without possibility of parole.

And while fans have been watching the show, some think they've spotted a mistake so big it could possibly give the rogue Starbucks cup in Game of Thrones a run for it's money.

Most of the series takes place in the 1980s and 1990s, therefore viewers were left baffled after spotting what they reckon to be doorbells with a little camera attached - something which is very 21st century.

"Well, nothing says the 80’s like a Ring doorbell. Solid work," one viewer wrote on Twitter.

"Now why is there a Ring doorbell in this scene set in the 80s?" another pointed out.

A third remarked: "Nah because he f***ed EVERYTHING up, like EVERYTHING. A Ring camera is INSANE."

Meanwhile, a fourth claimed they must have 'teleported 30 years into the future for this scene'.

Despite the show's popularity, it's not been without some controversy, however.

In a statement released via his wife, Erik slammed the show for spreading 'blatant lies' which he believes was 'done so on purpose'.

It read in part: "I believed we had moved beyond the lies and ruinous character portrayals of Lyle, creating a caricature of Lyle rooted in horrible and blatant lies rampant in the show.

"I can only believe they were done so on purpose. It is with a heavy heart that I say, I believe Ryan Murphy [director' cannot be this naive and inaccurate about the facts of our lives so as to do this without bad intent."

As well as Monsters, another Netflix documentary is set to be released which features the brothers telling their story in their own words.
