I’d never heard of this British sitcom before, but caught a few episodes on a flight.
It stars Nick Mohammed (one of the coaches from Ted Lasso; he's also the creator) as a hapless, low-level GCHQ employee, and David Schwimmer (Ross from Friends) as an equally hapless — but arrogant and self-important --NSA liaison.
It is genuinely very funny. Schwimmer is essentially playing an overboard version of Ross, which was nice to see again. It’s workplace comedy set against an espionage theme, which is a fun background juxtaposition in the first place.
It only ran for two short seasons totaling 13 episodes.
