The HBO series Last of Us is about a fungus pandemic. Unfortunately, it is much like The Walking Dead. The female lead who can save the world is a lesbian. Of course.
LoU is worse than you describe. An entire episode is devoted to a love story between two men which had no bearing upon the plot whatsoever.
Say ‘agenda’. Don’t watch LoU. I quit after fast-forwarding through that episode and having performed some due diligence research on those behind the series.
