Wallfisch used string orchestra to compose for the film, mimicking Bernard Herrmann's technique for the score of Psycho (1960), while blending synth and electronic music.

[5] Filmtracks.com reviewed "Wallfisch's The Invisible Man is hypnotically gorgeous and gratingly repulsive all in one, forcing the listener to edit together 15 to 20 minutes of the score's more effective half on album for a worthwhile tribute to the suspense masters.

"[7] Zanobard Reviews wrote "The Invisible Man isn’t a perfect score by any means, but it is an effective one – where it does succeed, it does so incredibly well.

The deep, in-your-face electronics for the titular character in Cobolt, the sombre, eloquent strings that add an eerie edge to the calming finale of Denouement – these are some excellent examples of where Benjamin Wallfisch really hits the mark here in his atmospheric musical effort.

"[8] James Southall of Movie Wave wrote "It all comes together into a score which on the one hand is a seriously impressive execution of a vision, and on the other is one I never want to hear again".

[9] Film Music Central wrote "Wallfisch really appears to be ratcheting up the tension with this soundtrack as well, as each track is just full of it.

Even the tracks that don’t contain references to the Invisible Man are full of subtle tensions (which you would expect in a horror film), as if the next encounter could happen at any moment.

And so, while the sound design adds plenty of atmospheric tension within the context of the film, the score as heard on the soundtrack album does little more than induce headaches.

A soft piano interlude (reminiscent of James Horner’s Flightplan) appears occasionally to offer a slight reprieve from the chaos, but otherwise there simply is not enough material here to warrant praise.

"[12] Jack Pooley of WhatCulture praised Wallfisch's score commenting that "it is employed to brilliantly bombastic effect at a number of critical junctures - especially during the more chaotic third act - in turn evoking the operatic tenor of the earlier Invisible Man movies.
