I think it's a good thing, but they need to have an extensive campaign of letting everyone know that the law has changed, and an easy way to opt out. Personally, I think what happens to your body after you die doesn't matter, and if you can help others with your left-over warm meaty parts, then great. But I do see how it could be upsetting for others, especially if they were unaware the law had changed and they could have done something about it. So yeah, make sure everyone knows, and let people opt out easily, but hopefully there'll be lots of good juicy organs for everybody!
