If you don't expect the funniest jokes of the century and can live with the same basic story over and over again (a (stupidified) Orochimaru tries to destroy Konoha, just to be stopped by Lee, Tenten and Neji - and also "guest-stars" from all of Naruto Shippuden), it's pretty enjoyable:
Similiar to "Family Guy", there are a lot of cutaways (Rock Lee's non-chakra version of genjutsus) which present the characters in recurring roles (e.g. Neji being shown as a school-girl or as his alter ego "Nejiko") that deviate a lot from their usual personalities.
Just be warned: The 2nd season's opening song is one of the worst you'll ever hear.
