Those would fall under your request for something interesting maybe... Nagasarete Airantou and AIKa R-16? Nagasarete Airantou is a cute story based on a guy being shipwrecked on an impossible to escape island full of female only inhabitants who haven't gotten any in awhile. Your typical "harem" genre. AIKa R-16 - Virgin_Mission, a recent one that came out, has lots of... welll nothing that would cross to illegalness but pretty much it falls in line with another anime Najica Blitz Tactics.
Naruto? Its way too long of a stretch and it is the new DBZ of today with a bunch of episodes with a bunch of unneeded silence build up moments and fights that just gets old using the same old formula over and over. Its sequal is not any better either, a same thing under a different name.
:thumbsup: to The Melancholy of Haruhi Suzumiya. Short but sweet and gets you thinking a bit about what the heck is going on here. Another good one is Lucky Star with all of its subtle presented humor about things with anime, games, etc. Great Teacher Onizuka is also a very good series.
