Well, something doesn't have to be BAD to make people angry. A lot of the time anger is based moreso on the thought behind the idea, fan reaction or some other issue. I personally enjoy the Wii, and it has plenty of games I enjoy as a low-end next gen option. It has quality games, decent variety and affordable product. That said, I dislike motion sensing and don't see why it couldn't have been offered with stronger system power, anyway. Aside from Nintendo games...when I get a 360 or PS3, no game on both systems is viable on the Wii.
But really, as a Sega fanboy....I keep hoping for a Dreamcast 2. So, I'll just say my opinions can probably be disregarded anyway.
