I enjoyed it and watched from beginning to end...
It was amazing to see the First Nations welcoming all the athletes to their home. The dancing was amazing and I was in awe with the music and costumes.
I also greatly enjoyed the high energy of the fiddlers and dancers. It made me want to get up and dance with them (though I didn't because that would not have been a pretty sight

). They really needed something like that to pick up the energy and get the excitement up.
I enjoyed the prairie, though I do think it dragged on a bit too long. After the high energy of the part before it, it was too long and too slow. Beautiful, but I think it could have been shorter.
Then the poem... I am not Canadian and have never been to Canada but the poem really stirred me. I loved the energy and emotion that it had. And the mountains and snowboarders that preceded it were also a lot of fun.
Overall, I think it was a success. The visual effects were amazing, simply stunning (the constellations, totems, breaking of the ice, and the whales were wonderful). Some of the performances were eh, but others were beautiful (personally, I enjoyed the rendition of O' Canada). This opening ceremony was more real and less... flamboyant. I think it was the right direction to go in. There is no reason a country should have to spend billions just to be better then the last country. If people are unable to appreciate the ceremony because it cost less money and was less "flashy"... too bad. The beauty and culture was there... and I thank the people of Canada for such an interesting opening ceremony.
