Yes. There is about 1 volume left to cover and the last 1 hour also covers about as much. Tbh I think it's worth it for a series like this. I was an AoT hater for the longest time after S2 but now that it's ending, I think it's one of the greatest pieces of literature I've ever witnessed. The way the story unfolds is unlike anything else I've ever witnessed in any form of media.
