Creator Reggie Rock Bythewood constructs a world so richly realized that there’s no doubt in our minds it existed long before we were invited in, and will continue to exist long after we leave. Add vivid characters and sharp storytelling, and it takes only a few episodes for Swagger to establish itself as one of the best new series of the year.

Whether you’re a basketball junkie or a casual fan, “Swagger” is an instantly captivating and authentic dramatic ride.

Swagger is a realistic look at how a talented kid becomes a superstar in the youth basketball world, but at least learns how to be a fully-realized person if basketball (more than likely) doesn’t make him rich.

“Swagger” might have one manufactured conflict too many, but when it settles into the stories that come naturally from these kids dealing with an uncertain future, it shines.

Like a lot of shows about young people, “Swagger” has a habit of repeating itself a few too many times to make sure the message lands, but it never succumbs to its sizable “After School Special” potential because of Bythewood’s emphasis on people over theme.

It can be a lot to absorb. But “Swagger” juggles its load thoughtfully, and it does what episodic TV must. It keeps you looking forward to the next chapter. On the court, the series meets its mandate to emphasize drama and excitement over realism.

Swagger has its moments. Yet for the most part, it plays more like a second-tier series than a blue-chip one.
