The standout feature of this episode is that David is the only non- African American character in the whole cast. Don't get nervous, though; though the race issue is brought up, it's not the driving theme. Black characters are allowed to simply be themselves, not mere representatives of their genetic grouping.
So why did I say the standout feature of the ep is all the black people? Well, in part because there's a fair amount of blaxploitation stylistics here, and in part because aside from those stylistics, this is a by-the-numbers episode. David works a small- time job (washing cars), makes a few friends, one of the friends has a problem (he's a 16-year-old illegally acting as his diabetic little brother's guardian), and they all run afoul of this week's gangster. The only thing missing is a love interest for David.
It mostly works very well, mind you. David does an even better than usual job as a father figure in his dealings with the 16-year-old guardian and his bro, and the considerable-sized cast are all given their own distinctive characterizations. The scenes are entertaining, and the dialogue works.
However, there are two humongous plot holes. Halfway through, the gangster has his head thug beat up David - for no reason at all! You get the sense that after a lot of head-scratching, the writers just shrugged and said, "Well, we've got to get some action moving in this episode *somehow*." Second, at the end the gangster pressures David's friend to deliver some explosives set to go off in 20 minutes. The explosives never go off, and we aren't told why.
