i think it would have been hard to put some serious plot development into these chapters as it was more or less a fighting arc, seeing how these certain characters have progressed since the chuunin exam. i very much liked them. not really disappointed. i think the next arc is where alot of plot development is going to happen. and cant wait till they start rolling out the chapters so i can read.
the anime is very disappointing atm im thinking of how they can get back onto the manga, something needs to happen between naruto and sasuke, .i also think that this filler arc in the anime is going to finish soon as the current manga arc is coming to a close.
