"Variety" magazine's Justin Chang thought that Blitz displayed a "terrific ability to embrace people's idiosyncrasies, real or fictitious" and called the cast a "strong ensemble", commending Thompson, Kendrick and D'Agosto in particular.The "San Francisco Chronicle"'s Peter Hartlaub thought that the script "never fails to present an unexpected scenario – usually accompanied by a moment or two of hilarity", but felt that Hal's ultimate failure was anticlimactic and "frustrating for moviegoers who prefer tidy endings".
