Sometimes it feels like being a teenager is an endless pit of existential crises as one tries to figure out their place in the world. Emily Dickinson, in the hilarious “Dickinson,” epitomizes the angsty teen, but she takes it a step further with her poetry. Belly is not quite as angsty as Emily, and they’re separated by centuries, but both share a need to be understood by their friends and family who still see them as a kid (or just a girl, in Emily’s case). The way they assert their independence and prove themselves sets the tone for both shows, whether it’s by sneaking out, being with someone they’re not supposed to, or going places they’re not invited.
