Is it an allegory for American teens living with the possibility of school shootings?
I really enjoyed it, the script is funny and light and the characters are easy to love. It has such a sweet romance too.
Obviously the premise (that kids in the final year of senior school are spontaneously exploding) is quite weird but if you suspend disbelief on that then the rest of it makes reasonable sense. Especially if you substitute school shootings for spontaneous explosions. The way the Govt guy talks down to them as though they were pre-schoolers and then says 'thoughts and prayers'. The way that the kids are dealing with not knowing if they'll live to graduate, let alone to adulthood.
