I can see both sides of the argument here. DKC Returns also comes with the problem that, unlike NSMB Wii, it's not bringing in a new ability with the motion.
I think much of the agitation from the side that's fine with using motion is because we're chomping at the bit for more good motion controlled games, and every hardcore praised game that comes out with GCN or CC controller options just slows down the process. Instead of more and more impressions about how the motion was implemented and then refinement, at least half of the impressions are just ignoring motions or calling them too much of a hassle.
Goldeneye is a perfect example of a game that's literally just pandering. It's not helping much at all by having that CC Pro bundle when at least half of the point of putting an FPS on the Wii is using the pointer.
Monster Hunter is another example that bothered me. The CC Pro bundle and the impressions other fans of the game gave of it, plus knowing about the "Claw" and other control issues with the PSP installments of the game, turned me off of it. The early videos of the developers showing off their motion control for the game didn't come off as very fun or exciting, although part of that is also caused by a lack of context over the frequency of certain actions in the game. The game came out, and I didn't even play the free demo I picked up from Gamestop. In the end, a friend push me to try it and I had a free slot on Gamefly for the foreseeable future, and I decided to give it a try.
The motions for that game are simple. You simply change the orientation of the remote, press the A button, and you get different attacks. Through the course of a combo, you either have to twist your wrist once when it came to the faster weapons, or back and forth for the slower weapons. In the end, the controls became half the reason I enjoyed the game. Now I'm not even sure if I want to get the upcoming PSP game since not only will I have to learn the button combos I was trying to avoid from before, I also will have to deal with the "Claw".
The worst part of this story for me? After my friend got me into it, I turned around and got three other friends into the game, and the five of us in total would play online in a rotating schedule, as we all had summer jobs or classes and couldn't all play every night at once anyway. I'd also see these guys some weekends for other games like Rock Band, and whenever the first one or two would arrive, we'd try some of the offline multiplayer mode. I soon found that I was the only one of the group that had even given the Nunchuck a try; they all instead got the CC Pro bundle. I'm extra annoyed at Capcom for deciding not to allow bowgunners to use the pointer to aim if they're playing Nunchuck style, citing it as an unfair advantage. A.) It's a cooperative game and B.) So what? It would have brought more people to give their control scheme a try.
I'm left thinking, what's the point? We need more games that make these motion controls worthwhile. Otherwise, the Wii might as well have not existed. Even games that have established themselves on dual analogs can become something different and entertaining on the Wii, as we've already seen the potential in FPS games and kart racers. Monster Hunter Tri has become my most played game on the system, and my second favorite overall, only beaten by NSMB Wii, another game people complained about not needing the motion and that it could have been handled by a button press. I'm hoping that DKC Returns can at least take third.
