Even though it was annoying as shit if you were a fan of the manga and watching Shippuden while it aired, it still did a good job with its early filler by using it to expand on characters/plot points/relationships that didn't get enough focus in the manga. But then after the Pain Invasion arc it went right into horrible meaningless filler territory that just unnecessarily padded things out, and it got even worse in the 4th Shinobi War arc because the manga had literally already ended so it was especially pointless. And the final arc got massacred by filler constantly breaking up really important shit and even coming in the middle of fights.
Also Nerissa just said Omelette du Fromage, that brings back good memories.
