In a way I can see why people don't want us to criticize. Not that I agree, no. But I understand because I am a highly uncritical person myself. Before the ending came along, while I agreed with some of the criticism, I really hated how negative people were about it. I was like "we're fans, seems like it makes more sense to try to see things in as positive a light as possible"--I'm not saying that this perspective is correct or the "right" perspective, it's just how I tend to see things. Everything, really. It's in my nature to see everything in as positive a light as I possibly can.
The ending, though, destroyed so many things I enjoyed that I don't mind being more negative about it.
