I think what does/did piss some people off was the fact, that they excpected something different from the wii, well at least people like me who got bought the wii, without knowing that it would be a casual console.
I wouldn't bother wasing money on casual games, seeing as i i can play them for free on the interwebz, and i didn't find wii sports interesting for more than a few hours, but whatever, i don't loose money because someone else pays for bejeweled.
For a while i was kinda pissed. i can live with the wii beeing graphically inferior to 360/ps3 because if u actually care about the game and not the shiny-factor the graphics are not limitating the wii games, just like i don't think dvds have gotten worse because blu-ray is visually better (though i would ofcourse watch blu-ray over dvd if it wasn't for the fact that i had to pay shitloads of money for a 1080p tv, a blu-rayplayer/ps3 and blu-ray movies)
But what pissed me off was the abscense of good non-casual games on the wii.
Now im not really pissed anymore, i've currenty got LoZ:TP (which was a fanboyish reason for picking the wii)mario galaxy, no more heroes and smash brothers: brawl, which in my oppinion are all great games (and red steel which is... less impressive). i'm planning to get force unleashed, and i think deadly creatures and madworld looks exciting as well, so between work, friends, girlfriend, other hobbies, more work and other stuff i actually have more games than i have time to play, i haven't even gotten to crack open the copy of metroid prime: corruption i picked up cheaply half a month ago.
I've got friends who's got the PS3, and they don't have shitloads of good titles either, because most of the games for the PS3 are also quite bad, especially when compared to the good PS3 games, I wouldn't wanna buy 5 different space marine FPS games, becasue frankly i find most single player FPS's quite booring (also i don't like most analog stick fps, PC FTW), and i prefer to stick with a few multiplayer-games at a time, since i usually end up spending countless hours on multiplayer games, and i just don't have time to play countless hours x5 (currently most of my game-time is spend playing DotA)
Back to the wii, another thing that bothers me is the wii-mote... when i got teh wii i was as excited about it as cartman in the cartoon wars dual episode of South park (freezez himself to get past the w8-time b4 the wii comes out) but i just don't see it living up to it's pottential, though i'm still hoping force unleashed is good, getting it soon.
Instead of using it apropriately, it has become just another button, for instance,
"get out of this hole in the ground - shake the wii mote
do a backflip roundhouse-strike - shake nunchuck
backflip over barbed wire while throwing a hatched midair and hitting ur target - join spetznas... oh w8, that has nothing to do with the wii...
I liked how the wii-more works in LoZ:TP, u use it to swing ur sword, use it to aim with your bow, it's mostly there when it needs to be there, and not just OH it's a wii game, make sure to cram as much wii-mote-wanking in as possible. i also hope/think that that's the case with force unleashed, seeing as the wii controllers are BEGGING to be used for lightsabers/swords and spells/force-powers
also, i read somewhere that sega was planning on making wii-games more appealing to the hardcore crowd and not really care about casual games (easy games) and fammily-friendly games, which basicly means games stripped of any sort of violence so the little kids can play them without mommy suing.
Just look at the prewievs og madworld, u'll know what i mean.
In the end i guess my point is that there are good games for the wii, and i don't think the wii will end up beeing a no-go consule for any1 not casual.
