yeah its pretty cool how they used the flashbacks to sorta show how everyone's connected to each other. I think the demon guy looking like the fourth is just coincidence....since im sure that even though its the 4th's jutsu, the god of death has been around a LOT longer than he has. That WAS actually a type of summoning, wasnt it?

anyway, the temari vs sasuke match didnt happen in the manga, so thats a nice little addition, but aside from that new song they had near the end and all the cool flashbacks of other konoha ninjas, i didnt care too much for this ep

oh....and while it certainly looks like a hokage holding baby naruto.....it could just be in reference to the 4th sealing kyubi into naruto....although the eyes and hair seem to bear a great resemblance between the two....i dont think we can jump to conclusions just yet
