LOL. I want to read the mangas, regardless of things they may change (although I do hope they don't get carried away).
So far in my experience with Clamp mangas they do a pretty good job. I watched the anime over the summer (renting it DVD by DVD). It was so wonderful. It made me remember when I was a little girl and wanted my dolls and such to come to life. Ah the good old days. Anyway, the anime is the only thing that kept me sane from my job. In my opinion, Clamp is notorious for their good work.
