[7] Charles Spencer in The Daily Telegraph saw this production as "a notable RSC debut" by Fentiman, "with just the right mixture of dark wit and in-your-face violence".

[16] Michael Billington in The Guardian gave Loot a five star rating, commenting on the way Fentiman referenced the "shock tactics" in Orton's work.

[18] A contrary viewpoint was taken by Alun Hood for WhatsOnStage who believed the production "[throws] fresh ideas at [the play]" and "will likely infuriate as many people as it delights"[19] Henry Hitchins in the Evening Standard mentions Fentiman's "at times racy interpretation [that] suggests the anarchy seething beneath Wilde's polished witticisms".

[23] In October 2022, Fentiman directed Audrey Brisson in Reading Rep Theatre's production of Jekyll & Hyde, Gary McNair's adaptation of Robert Louis Stevenson's novella for solo performance.

He directed Forbes Masson in the role of Gabriel John Utterson when the play was staged at the Royal Lyceum Theatre, Edinburgh, in January 2024.
