Broken Base: Over Autotheism. One half of the fanbase sees it as a bold new progression of their sound and the album that Keene truly wanted to make, while the other half sees it as boring, pretentious, derivative garbage that shamelessly rips off Opeth, Cynic, Devin Townsend, Extol, Porcupine Tree, and Theory in Practice with a lyrical concept that embodies the worst stereotypes of atheists.
While In Becoming a Ghost has been better-received overall, it managed to spawn another one of these. It's either a challenging, eclectic release with a ton of things to discover that still nonetheless stays faithful to their established style, or it's a scattershot, unfocused mess that can't settle on an idea without abandoning it for no good reason and then going off in a completely random direction that makes zero sense.
Face of the Band: Micheal Keene for being a case of I Am the Band, Ken Sorceron for his work with Abigail Williams and Lord Mantis, and Justin McKinney for his work with The Zenith Passage.
Gateway Series: Along with Death, Necrophagist, Obscura, Revocation, and Archspire, they are one of the most common entry points into tech, and The Faceless in particular was responsible for getting a lot of deathcore fans into tech with Akeldama and Planetary Duality.
Never Live It Down: Michael Keene's entire behavioral problems, his drug issues, and his actions that lead to the band's never ending line-up inconsistencies and egotistical nature alongside being an Insufferable Genius really paints a negative light on an otherwise talented band.
Overshadowed by Controversy: From 2016 onward, the band has been known more for Michael Keene's out-of-control drug problems, repeated tour cancellations, dodgy and frequently terrible live performances, extremely frequent and almost always highly acrimonious splits with former members that frequently involve a significant amount of drama (particularly Chason Westmoreland, Ken Sorceron, and Justin McKinney), and reliance on session lineups than for their music, with the Bay Area Deathfest fiasco being the absolute nadir of their career. While their summer and fall 2018 tours have been somewhat well-received and have managed to repair some of the damage, it is unlikely that people are going to forget just how much of a mess the band was over that stretch any time soon.
