As with everything, the experience you get will heavily depend on your opinions and expectations ...
Someone who walks up to the Wii U and is of the mindset "Let's look at how crappy this system is" will likely find, or create, reasons to dislike the system; at the same time, someone who walks up to the Wii U and is of the mindset "Let's look how awsome this system is" will likely find, or create, reasons to love the system.
Now, comments like "Graphically speaking it doesn't meet my excpectations, the aliasing is horrible and the modeling looks poor" caught my eye primarily because I haven't seen any screenshots or videos of ZombiU that demonstrate aliasing, and when someone makes an inprecise claim like "the modeling looks poor" it is usually because they're trying to find something to support a conclusion they had ahead of time. What is it about the modeling that "looks poor"? If it is lacking in some technical way than it is easy to support using visuals (like screenshots or videos), but if you just dislike the artistic direction than it is not a really valid point.
