I don't think you have to be insane... I just think you have to have zero tolerance for motion controls. That seems to be the case with all of 1UPs reviews, regardless of system (Lair anyone?). I remember a 1UP show a while back where they spent half the show bitching about the motion controls in the Warhawk beta. I played that beta on a friend's PS3, and although the learning curve was steep, the motion controls were very smoothly handled.
Similarly, any game that makes heavy use of motion controls is criticized very harshly. If you read their MP3 review, they constantly bitch about the motion control actions. I have been playing for over 10 hours now (in fact I have the game on as I'm typing right now) and I can tell you that the game reads the motion controls very smoothly. If you aren't ADHD and actually pay attention to what you are doing you shouldn't have any problems executing all motion commands effortlessly. They gave Wii Sports a 6.5 because of the motion controls, despite it's industry average being a 7.7. I think what they are against more than the Wii in specific is anything that changes their limited view of what gaming "should be."
I haven't yet run into a single spot where Metroid uses motion control. Any of the "pull and twist" or "interact with object" things thus far have used infrared exclusively.
SSX Blur used motion control an awful lot, and it took a lot of learning to get used to. My fiancee had been a big SSX fan and hated Blur for the first hour or so, but after she got used to the controls she loved it. It's her favorite one except possibly Tricky, which she still loves. I loved the game from the beginning because I had no preconceptions about how the controls should work and was happy to learn them.
It sounds to me like 1up is just unwilling to try new things regarding gaming. The problem is that they're not hardcore gamers. They don't want gaming to change because it's easy and requires no thought to just keep doing the same thing. If they were hardcore gamers, they'd welcome all kinds of changes to gaming and realize that the best mechanisms will always exist -- motion or no motion, infrared or no infrared.
While I'd agree that we're still looking for an appropriate place for motion based controls -- Godfather is a good clue as to where to go -- it's clear that infrared and pointing based controls are in the future and will be bigger as time goes on.
