The original batch of naruto was an extremely enjoyable series, but now is when it gets truly good. The start of shippuden is a little bit slow and yes there are a few filler episodes, but it all adds up to you getting back into the swing of things. The characters are, as ever, very well put together. I enjoyed all of series 1 and the following few volumes also. I would recommend this to ANY anime fan even if they haven't watched the earlier series. Very easy to watch!
