I think the way the specials are made is way better than the actual anime. It captures the essence of the manga separating the episodes in small stories rather than trying to connect everything in a 20 minutes episode filling the gaps with something. The actual anime is enjoyable tho, but I think the specials are closer to the real thing and better made. If by any chance they made a second season I would love if the studio keeps this format, not because is more similar to the manga, but because it makes the jokes and the story easier to understand.
