I'm loving this series so much, I never thought the animators would make it so humorous and I feel that I wouldn't mind watching this as a Naruto Shippuden filler since the series is currently undergoing in filler territory at the moment so what's the harm with having some Rock Lee filler lol and besides it would stall more time for the manga to get even further ahead than the anime.
it would be fun every once in a while but having the " Lee and friends " filler for more than it should would be worse
I really love this series myself actually i look forward to it more than i look forward to Naruto episodes specially now that it entered a series of stupid, repetitive fillers again
