Musical Hell runs in tandem with two spinoffs: Know the Score, a Lighter and Softer companion piece that discusses soundtracks, film and stage musicals, theme songs, and any other form of dramatic music” that happens to strike Diva’s fancy; and At the Source, where Diva discusses materials that have been adapted into musicals and any changes made in the adaptation process.
In 2023, Esterle announced (in-character) that she would be ending the show and retiring the Diva character in 2024.

Musical Hell provides examples of the following tropes:
Know the Score contains examples of:
- Catchphrase: "Hi, I'm Diva from Musical Hell, and I know the score!"
- Lighter and Softer: Rather than playing the role of Caustic Critic for musicals that are at best misguided or weird and at worst borderline unwatchable, Diva explains what makes some of the best musicals what they are or examines the use of popular musical theatre narrative tropes (for example, one video is devoted to the Eleven O'Clock Number, another to the concept of the "I Am" Song and "I Want" Song).
- Ominous Latin Chanting: The opening theme is "O Fortuna".
- Public Domain Animation: The title sequence.
- Signing-Off Catchphrase: "I'm Diva, I know the score, and now so do you."
- Title Drop: It's right there in her opening and closing lines: "I know the score!"
