This one took me by surprise. The opening sequences, with their funk music and story of a has-been race car driver turned mechanic who stumbles upon a stash of mob money in the trunk of a car he's working on, had me convinced this would be a solid but by-the-numbers episode. In a sense it is, in that you have all the usual elements: drama, heart, human interest, and the contrast of the calm collected David and his raging alter ego. But it doesn't play out the way you'd expect, and it's consistently excellent on every front.
To get to a job interview at a lab, David takes a job driving someone's car up to New York. It's funny; the first time I heard of this strange-but-true job was in a 1960s Hulk comic in which Hulk sidekick Rick Jones takes the very same job, and similarly becomes a criminal pawn because of it. Cue road trip pursuit, roadside fights, and a waitress who hitches a ride with our hero.
It's a pretty standard setup, sure, but again, it doesn't unravel as you expect, and it's surprisingly compelling. The waitress's estrangement from her young daughter is handled with convincing tenderness and the villain of the episode, despite being a standard issue mobster, is genuinely scary, giving great intensity to the climactic scene.
A favorite scene of mine is when David calmly talks an angry trucker into backing down. Just a wonderful demonstration of how the greatest hero is one who keeps his cool and chooses peace even when he has the power to knock your block off. Yet the whole episode is superb. Watching it a second time prior to writing this review, I find my opinion of it has only improved.
