This was the by far the best part of any outside content from the mainline show. I felt attached greatly to Levi and his friends in just the two episodes we get. It builds on Levi's character greatly, especially after finishing season 1 and further after season 3. The pacing never felt rushed or too slow and the story felt believable and was highly emotional. Very on par with the main seasons. It is the only outside content from Attack on Titan that feels like you walk away from it learning more about a character and even elevates main series scenes.
