The ONLY valid complaint you've seen leveled against Okami is Issun -- and I find Midna nearly as obnoxious. Wah wah drawing simple shit bugs you -- it's a lateral shift from selecting items with a menu, much as waggling is a lateral shift for button pressing in the Wii version of TP.
Okami has fresh characters, fresh mechanics, a vibrant art style, brilliant graphics, great integration of the overworld and puzzle dungeons, a fascinating retelling of Japanese myth, and a deep (for the genre) development model.
Zelda 2006 has tired characters, retreaded mechanics, an honestly questionable visual style and technology, AWESOME dungeons but a horrible overworld experience with progress blocked by countless distinguished mentally-challenged mini-games, and more of the same overall.
Both have annoying sidekicks that drive me fuckin' batty. Neither game is very difficult, either.
Fortunately, it's a same I *love*, but of the two, Okami is the far fresher experience, and one I'll remember. TP will probably be forgotten after I finish it unless my mind suddenly gets blown -- and I'm halfway through the game, now (just beat the Arbiter's Lair and the skeleton boss).
