This is the third time I've read this book and I decided to read it in Portuguese. It was awful. The names of most characters were changed, plus the linguistic jokes got lost in translation (Diagon Alley, the Sorting Hat saying "I'll eat myself"...), so I decided to switch to the illustrated version half-way through. The illustrations add such beauty and magic to the story that I'd say it's the best version of the book. Unfortunately I don't have access to the rest of the illustrated series, so I'm not sure if I'll continue my re-read.
