However, in a year where X Factor has struggled to reach its usual sizzle, Rylan's bizarre fashion choices, bombastic routines and ever-changing (facial) hair have provided some rare moments of colour and surprise.
Digital Spy has collected together our personal five favourite Rylan moments from the series to celebrate/commemorate his demise from the show.
Rylan says hello to the Live Shows
Martin Kemp probably thought he had suffered enough after a stint in Celebrity Big Brother. Little did he know Rylan was around the corner, dressed in a gold sarong with a wheezy take on 'Gold' that has to go down in X Factor history as one of the show's worst ever vocals. Terrible? Yes. Memorable? Certainly.
Rylan gets one over Gary
His comment about Gary's weight caused some serious cackles from Louis Walsh's end of the desk, but we preferred Rylan's brief cover of 'Back for Good' as his finest comeback at Gary. Oddly, it was probably his best vocal of the whole series.
It wasn't a surprise to discover that Rylan's musical heroes were the Spice Girls - the original queens of musical commercialism and cheap gimmicks. His Spice Girls medley had about as much musical credibility as a Teletubbies single, but we swear we could even see Gary Barlow swaying along in the choruses.
The first audition
The one where Rylan admitted that he was a "borderline drag queen", debuted some appalling blonde locks and declared that he cared more about getting his "foundation colour right" than eating proper meals. Rylan's first audition and VT showed him to be self-obsessed, attention-seeking, vain and a pretty awful singer. Did anything ever actually change?
That crying face
A match for even Claire Danes on Homeland, Rylan's reaction to making the Live Shows was the finest ever piece of ludicrous and irrational reality TV hysteria. Anyone would have thought he'd found a cure for cancer rather than progressed one further stage in a knockabout TV talent contest. Nicole Scherzinger's what-the-f**k-I-have-done face rounds off the clip nicely. The whole sequence deserves an Emmy.
