I thought the Prince of Tennis anime was pretty good.
Prince of Tennis was an anime I used to watch religiously. I was the kind of guy that would idle in the anime-otaku irc channel an hour or two before release and be one of the first to snag their DLs of the bot. The anime started off very well and carried itself fairly well to the end. All the characters were very well explained and they were bad ass too! Tezuka ftw.
Yeah, I do agree with you that there is a lack of some good new anime. And I also agree with the fact that 13/26 ep animes are just horrid. When it comes to the 26 ep animes, I find myself slowly starting to enjoy the character development and storyline just to be simply shotdown by the abrupt and rushed 26 ep ending.
With the limited options, there isn't much to view. But if you are the kind of guy that generally enjoys Shonen type anime, I highly recommend Hunter x Hunter. The anime, imo, is perfection. The anime has all the necessary essentials of being a solid underdog shonen style anime; no filler garbage, solid character developments, thick plot, massive and epic battles, and edge-of-seat style extra bad-ass enemies. The anime is relatively old and is hard to get, but i would highly recommend it.
There are other options too. Honey and Clover is a typical 26 ep anime but the story line, humor, relationships within characters, and the overall plot flow perfectly. Its sort of a love-anime but it isn't even remotely close to the average harem stuff like Love Hina, Shuffle, and the typical stuff one would expect to see. Its unique in its own style and is rated very highly on anime sites.
Hmm, a website i'd recommend you take a good look at is www.animeacademy.com . The site is run by passionate anime fans that have seen a LOT MORE than an average anime lover. Anywho, these passionate anime fans critique the anime in a proper, unbiased fashion and give it a letter grade. So it would be very easy for you to sift and find what you like. The only pain would exist in being able to find some of the older and more classic anime.
Hope this helps !
