There are so many clues that A Town Called Malice is a deliberate farce, the prime clues being the frequent scenes where the cast start singing to the backing music - true pastiche.
So the first thing we should be cognisant of is that this is a show that doesn't take itself too seriously. It's designed to take the mickey out of the times and the situations, and it does so with some gusto.
Amongst all this is a one family crime wave arriving on the Costa del Sol chasing riches with little care for the imprudence of their actions. They leave a trail of destruction in their wake, and come up against some stiff opposition, but they also give way to the comedic imperatives of the show - so the bumbling clowns get off the hook when in reality they would more than likely have parted ways with their heads.
The music is terrific, the show is outrageous - good times.
