A number of ITV viewers have been left switching off the channel's latest drama offering, The Long Shadow, after growing frustrated with certain aspects of the show.
With a cast led by the likes of Katherine Kelly, Daniel Mays, David Morrissey, Lee Ingleby, Charley Webb, and Jill Halfpenny among other big names, anticipation levels were sky-high prior to Monday's premiere.
The series has been billed by ITV as a "definitive depiction of the desperate five-year hunt for serial killer Peter Sutcliffe".
The Long Shadow "sensitively focusses on the lives of the victims who crossed his path and those of the officers at the heart of the police investigation", according to the channel.
ITV stated it had "the victims, their families and the survivors at the heart of this series" as it depicts the manhunt for the Yorkshire Ripper which took place back in the 1970s.
Episode one of seven got underway on Monday evening but several viewers appear to have already given up on the series thanks to sound and lighting issues.

As the drama unfolded on-screen, several took to the web to hit out at the sound issues.
One fan fumed on Twitter: "#TheLongShadow has an epic cast, but the sound mixing is dire."
While a second also hit out: "Dear #ITV when you commissioned #TheLongShadow did everyone involved watch it back? One minute the sound is very low, then it's to loud!!
"I can't make out what Katherine Kelly is saying, will have to rewatch it again with subtitles. #TheLongShadow should have gone to @Specsavers."

Another echoed: "#TheLongShadow - anyway else struggling with the sound on this? Can barely understand a thing they're saying!"
And a fourth blasted: "@ITV #TheLongShadow loving it but the sound is poor - background music higher than speaking in a lot of key parts #whatdidhesay? Missed most of it!"
Elsewhere, a fifth praised the cast but it wasn't enough to keep them hooked: "Some great actors on what is such a heartbreaking story but the sound is awful and ruining it #thelongshadow."
A sixth switched off altogether as they penned: "Given up. Sound too bad paired 1970’s lack of lighting… have no idea what’s going on. #TheLongShadow." (sic)
