I stopped watching Naruto last year in favour of getting back into the manga. I got to the 3-Tails arc and lost interest.
I haven't really watched anything for ages. I'm trying to rewatch Digimon Savers but again I'm losing interest (and I'm only an episode in). The last series I watched properly was Pita-Ten, but again, I preferred the manga. The animé was only ~26 episodes long, but most of them could have been skipped out. The alternate ending was interesting I guess, means I cried over two different forms of Pita-Ten.
