Mark Harrison’s review published on Letterboxd :
Are you OK, Mindhorn? It's just that, keeping Alan Partridge: Alpha Papa in mind, casting Steve Coogan as a character who did what the main character did but better feels like an entirely unwarranted self-own.
This is pretty funny stuff, written by and starring Julian Barratt and Simon Farnaby, who play their respective trademarks of desperation and sleaziness to a tee in a fun Galaxy Quest/Alpha Papa mashup. A couple of the big gags are telegraphed too far in advance, but short of a Darkplace movie, you get everything you want from this kind of thing.
