IMHO a lame-o review written by someone who doesn't know much about cars or racing, although it shouldn't be expected that he would. I do stipulate however that any dramatic narrative on Shelby's domestic life would have been unnecessary.
"In the tailoring of its story for untroubled consumption, it stumbles as much with its omissions as with its excesses." He got that right with the operative word being "stumbles."
