Want to know what's great about the Wii U? That nobody can figure out if it's good or not. There are arguments for both camps. Lots of people want it to become popular -- they're probably big Nintendo fans. Lots of people are rooting for its failure -- they're probably fans of something different.
Here are a few negatives that have come up in the last week since the thing launched, summoned from my brains:
1: The menus / apps load slowly.
2: It requires a 5 GB patch to go online.
3: The emulation of original Wii games is still in 480p and is not up-scaled.
4: The GamePad tablet-controller needs to be recharged frequently.
I'm going to take the high road on this and assume that the people leveling these criticisms are in the industry of leveling criticisms. They're paid to stand alongside, and consistently evaluate, potential fun-levels, like the manager of the guy that wears the Daffy Duck costume at Six Flags in Tampa, Florida. On the subject, that manager really wants a microscope for Christmas so he can finally try to find his balls -- and a mustache comb for combing his back hair.
I can't trust these people. They're hateful. I don't work in the industry of recommending entertainment, but you don't go to The Industry to get recommendations on fun and happiness. You go to some person that has one.
