Prisoners of the Sun

It's hard to rate this one. Since it was part of my childhood, it's hard to shake off the nostalgia. However, it's even harder to escape the prejudices of its time. Almost all Tintin comics are full of prejudice and racism, exalting the alleged intellectual and moral superiority of the white European man.

In this particular title, we see the courageous Tintin killing wild creatures in the forest, doubting that the “indians” can be medical doctors and deceiving the native population with his scientific knowledge. It's really hard to read these things nowadays.
