The song is based on the novel Nineteen Eighty-Four by George Orwell. There are several references to it throughout the song, one of the most noticeable being the reference to 2 May - the date on which the two main characters, Winston and Julia, first spend the night together.

It was featured on the soundtrack of "Radio Big" in the 2003 video game SSX 3. It was also released as downloadable content for Guitar Hero World Tour.

In 2010, Utada covered the song on her first US Tour, Utada: In the Flesh 2010.

"The Bitter End" and "Every You Every Me" are the two most often played songs in the Placebo's live shows.

Critics generally praised the single upon its release. Reviewing Sleeping with Ghosts, BBC.co.uk's rock/indie reviewer Dan Tallis described "The Bitter End" as "a good pop tune", having "just the right amount of dark, gothic atmosphere to please their fans and enough radio friendly guitars to please the new generation of indie kids." The Times thought the song "ramped up the energy level to devastating effect."

Rock Sound reasoned that the track's "kick ass romp" reinforces "their status as purveyors of pure indie pop in the vein of The Smiths." However, NME saw differing influences woven in the track, reporting that "The Bitter End" "sees Placebo powering along with a relentless U2- chasing-after-The Cure melody that's as infectious as 24."

Summarising Placebo's 2004 singles collection, Once More with Feeling, BBC.co.uk's Nottingham music reviewer Jaime Gill stated that "each song stems from a songwriter so instinctive and precise that when he writes a song called "The Bitter End", that's exactly what it sounds like."
