Netflix Viewers Left Horrified By 'Chilling' Nail Bomber: Manhunt Doc

While some have called it a "good yet sad watch", others have called it "shocking".

Take a look for yourself in the trailer below:

One viewer was so shocked by the real life story behind the documentary that they called it chilling.

"OMG I am watching the nail bomber documentary on netflix and I got chills," he wrote.

Meanwhile, a second said they were horrified by the actions of the bomber and admitted they hadn't been aware of the story before.

"What a horrifying and angering documentary," they wrote.

Another called it a "good yet sad watch" and this seems appropriate tbh.

A fourth wrote, "If you haven't watched Nail Bomber on Netflix, you really should," while a fifth called it "a really tough watch".

Sadly others were quick to pick up on how they'd had no idea of the events of 1999.

Calling the documentary "terrifying", one Twitter user said they'd had "no idea this even happened".

The documentary follows a series of bomb attacks that happened in the capital in April 1999, over three successive weekends.

Each bomb had up to 1,500 4-inch nails and went off in public spaces in Brixton, south London, Brick Lane, Spitalfields and The Admiral Duncan pub in Soho, west London.

Three people were sadly killed, while 140 others were injured in the attacks.

Nail Bomber: Manhunt also explores how perpetrator David Copeland was caught and brought to justice, with accounts of the three terror attacks and exclusive interviews with investigators, undercover informants, survivors and community leaders affected by the bombings.

Nail Bomber: Manhunt is available to stream on Netflix now.
