I watched Cardcaptors after I read the CCS manga and watched a couple of episodes of the anime.
While I watched one of the CC episodes (I think it was the slaughtered version of episode
, I just sat in front of the TV expecting at least something decent out of it. What I get though is pure b*******
  The voices sucked! And Nelvana cut out so many funny scenes, and "tried" to cover up Sakura and Syaoran's crushes on Yukito.
Many other CCS fans have sent a lot of (hate) mail to Nelvana asking them about the things they've altered in CC. They just said that they wanted to make Cardcaptors more "suitable" for the American audience, so that's why they made those changes. However, if they wanted to turn such a beautiful anime into a horrendous piece of c*** , then it would've been better off if they'd never laid their hands on CCS in the first place.
In another POV, Nelvana bringing CCS to North America under the name of Cardcaptors can also be considered a good thing because many of us would not have discovered CCS otherwise (even if it was the butchered version of it).
So, I'm not really sure whether or not Cardcaptors was
completely a bad thing
But I
can say this...CCS is way better no matter what they do
