Lambs Anger received mostly positive reviews, calling it Mr. Oizo's most complete and accessible work, with a few publications criticizing the album's repetitiveness and the lack of ideas.

According to Mr Oizo, the recording process went easily and he ended up creating "a lot more music than [he] needed", only keeping the best material for the album.

[15] Resident Advisor praised the album for being Mr. Oizo's "most intelligible offering ever", calling it "edgy yet consistent, odd yet easy to embrace".

[18] Writing for Spin magazine, Mosi Reeves applauded Mr. Oizo for creating a "sweaty, gleefully claustrophobic dance workout that celebrates the current electro-funk renaissance".

[19] Aylin Zafar of URB magazine called Lambs Anger "the pitch-perfect soundtrack to an epic night out" praising Mr. Oizo's use of samples throughout the album.

[20] Clash magazine called Lambs Anger Mr. Oizo's "most complete work to date", describing it as an "array of electro house tomfoolery".

Brian Howe of Pitchfork described the album as "overblown and frantic, with a surplus of sounds and a dearth of ideas", criticizing "rigid repetitions of a single basic theme" on most of the tracks.
