I had no problem with the characterization and voice work in Metroid Other M. I liked her being human rather than just a suit of armor with no fear.
I loved the Skyward Sword, but it's not perfect. There are three things I would change.
1. The option for classic controls.
2. Less backtracking, more environments, ie add a snow level.
3. Add voices.
I don't need Link to talk, but everyone else should. Gordon Freemon never talks but because everyone else does you end up with a far more convincing world than if they didn't.
The problem is that fans are never happy. They all have their ideas of how things should be and any deviation is a unforgivable sin. Nintendo can't make everyone happy. If they keep it all the same people complain it's not different. If they change it people complain that it's different.
Nintendo should just always use new technology to enhance the their games. We are no longer living in the silent gaming era so games should be silent. It doesn't mean every game should be an interactive movie like Uncharted, but all games should use their medium's technology to its fullest.
