Severance works well for learners who already understand English comfortably and want more challenging listening practice. Following the story requires attention, so language difficulty is not the only challenge here. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. Conversations usually leave enough room to process what is being said. If your English is close to C1/C2, Severance can be useful for building confidence with more complex narratives.
