From its first episode, “Plan B,” which debuted on Netflix back in 2015, “Master of None” has always been an experiment in metatext. The series, from co-creators Aziz Ansari and Alan Young, puts a spin on their own experiences growing up as first-generation immigrants, struggling to make it into Hollywood and navigating through all kinds of anxious “Is this growing up?” experiences, from uncomfortable first dates to career setbacks.
