the only question that springs to my mind is How and Why do you honestly expect people to justify for different gaming tastes? you like some games and dislike others well guess what - thats something PS3, 360 and Wii owners all have in common.
You say these games get bad reviews yet the Wii is a console that is set up in a lot of people's living rooms and not tucked away in a bed room cos it's more suited to multiplayer games than the others - now bearing this in mind and looking at the list of games you gave us as examples can you now see that all of these games with the exception of Links Crossbow Training and Pokemon and fun multiplayer games that can be enjoyed by a group of people.
As for the other 2 games Pokemon well the name should tell you this and it was the first Wii online game, Links Crossbrow training budget game that came with a free Zapper (or was it the game that came with the zapper).
Common sense should tell you this but I suspect you already knew this before creating this thread
