I echo the things people have said so far. I like the fact that the cartoons remain intact but still recognice that it's a product of a different era. I never liked how entire scenes where cut out of shows because of one little thing, but I also don't like it when people come across as "it's ok that it's racist because it's my childhood!"

Yes, Pippi's dad have always been a bit troublesome from a modern perspective. I doubt Astrid Lindgren had any particular race envelopes to push when she wrote that, it was just in the culture at the time; any white person would become leader by default if they made contact with tribals. But then again, Pippi's dad has always been a rather odd figure, with his connections to pirates and leaving his daughter to fend for herself and whatnot.
One thing about changing "niggerking" to "southsea king" that I like: Astrid Lindgren herself regretted calling him that, stating that it was "idiotic" of her in later years. If she was still alive I think she would've approved of the change. According to people who knew her she was a very open-minded, loving person who never judged other based on what they where.
