No sir, I don't like it.
I'll keep it short and spoiler free. This movie has one of the single most LAZY plot devices of all time. And, the entire concept is wrapped in a 'there is no way a lawyer wouldn't have been called' frustration. Not clever by half. Basically an opportunity for some decent actors to mug for the camera as loathesome family members. And, Daniel Craig, who has never been someone I enjoy, is the guiltiest party here. Using a slippery southern drawl that goes in and out, he proves to be one of the dumbest master sleuths ever.
POSSIBLE VAGUE SPOILER ALERT
The twist is only noteworthy for it's entirely unoriginal design which is further complicated by including a barely involved character.
