Can you give an example? Only one I can remember so far is previous the first Naruto and Sasuke fight at the hospital, which the anime used as a reason to make Sasuke leaves Konoha
The fight where Kakashi interrupts them by throwing them aside at the end? Was that really filler?? Anyways the most recent example is after the grave robber arc or whatever it was you start the arc with Kakuzu and the immortal dude and at the start Naruto and Sai were in the hospital after saving the village and everyone mentions how great they were.
