Personally I really loved these fillers. It added so much to the story and to great characters that we didn't get to see as much. I loved everything shown about Kakashi's character such as his difficulties with dealing with the death of Rin and not being able to keep his promise and his evolution to the Kakashi that we saw at the beginning of part 1. Everything else like Itachi time in the hidden leaf when he was younger and Minato's becoming hokage and yamato's backstory were also great.
They have done a great job putting it together and it's a shame that some people may not enjoy it as much or not even watch it just because they are labeled fillers.
