I know a lot of what I have to say about Nintendo these days is negative (even though I have enjoyed a few of their games recently), but that's just a reflection of the times. It's unlikely you'll find the forum filled with Nintendo praise when a lot of people aren't happy with the way things are going. It's just a sign of the times. At the start of the Wii and DS, these discussions really weren't around to the same extent because people were generally happy with what they were getting.
TL;DR try not to get down about it, other people's dissatisfaction shouldn't really affect what you think. And yeah, the positive thread.
