Jiraiya is also one of my favorite characters, because he is what Naruto is going to be, better even.
I'm sure you've all realized that the new Sannin's are going to be the old Team 7, and they're all training, or have trained under the person they are going to be like. Jiraiya even made mention of it again, when Sakura punched Naruto, "That strength, and that temper, she's just like Tsunade."
Anyway, it was a good start again to the main story, I really can't wait for the anime to be where the manga is, Ransengan Shuriken!!! there are some good things happening in between the two points, like meeting some other fav characters like Neji, and Hinata.
