Well, I'm going to disagree with the majority, but that's mostly because I hate games that artificially extend their length by not allowing you to skip dialogue (especially if it's being repeated because you failed a stupidly counter-intuitive puzzle) and essentially being one big scavenger hunt that coincidentally has a game included, too. Because that's what Okami is. It's a 12-15 hour game with 45 hours of scavenger hunts and fetch quests tacked on.
If that floats your boat, have at. At least with the Wii the controls shouldn't be aggrivating to learn even if they aren't all that great. Just be prepared to get involved in a lot of dull, repetitve combat sprikled in between a lot of dull, repetitve item searching while being accompanied by a dull, repetitve insect who you cannot shut up. I'd still say it's worth no more than a rental if you have anything at all better to do with your life, and only then if you've played the hundreds of better games available.
You do not have the right to never be offended.
