This television show is rather dreadful, I'm afraid to say. Rarely do I watch a serial and become highly irritated in the process.
The story moves somewhat too swiftly, and makes little to no sense when you engage your mind and think about the events occurring. There is an unacceptable quantity of foul language and profanity, particularly from an individual by the name of Angel Dust, one of the main characters.
The other characters vary in likability and depth, yet I cannot say I am a fan of our protagonist, Charlotte Morningstar, heir to the throne of hell. She is overly optimistic and barely listens to others, making her a prideful and selfish young woman you desire to wish failure upon.
The songs themselves range from masterful in both lyrics and tune, to utterly poor (the worst offender being "Speedrun to Redemption").
Overall, this television series is truly dreadful excluding a couple of the songs and characters, as well as the animation which is rather lovely.
Edit: ROME!
