"Tiny Mix Tapes" rated the album four and a half stars out of five, saying ""Mental Illness" proves once again that the only thing necessary to make a great rock album is that spark: that spontaneous, effortless charm which is impossible to duplicate, no matter how many producers or professional musicians one brings into the studio." "xsilence" retrospectively rated the album 14 out of 20, saying it was a hard disc to access "but not without interest, that only fans and purists are likely to appreciate its true value. After all, this vintage sound, is not it simply The White Stripes before their time?" They said "the sound is crappy [...] and that's really what gives charm to this disc." "Debaser" said that "this is not their best album," but "is definitely the disk with which it is worthwhile to know them. It's like a shooting star that cannot burn. And one of the disks that surely if we ever explain why the nineties are not just throwaway we could take as an example."
