MINISERIES PREMIERE: The first season of HBO’s Westworld established that there were other amusement park “worlds” that were part of this troubled, part-android universe. To keep fan appetites whetted until the second season begins, HBO is presenting this limited-duration miniseries, set in an intense, isolated facility where visitors – the type who love to play videogames and computer chess, and compete against artificial intelligence – are placed into dehumanizing testing centers to compete with SAT-type standardized tests. Only visitors who score in the Top 10 percent move on to the next level. And those who score in the Bottom 10 percent are forced, before returning home, to spend two days working in Fastfoodworld.
