I noticed a lot of people didn't like the Kage Summit arc but for me it was one of my favorites. I loved the interaction between the Kages and also how Tobi bursted into Naruto's hotel and divulged all the info about Itachi to them. What I really liked was when Sasuke snapped and just turned evil lmao. At first I didn't like it because it was a complete 180 degrees but it grew on me quickly. As soon as Sasuke stabbed Karin and Tobi was like "that's my boy", I became a Sasuke fanboy lol.
