It's weird, but I think I have a harder time with dubbed-over dialogue than with subtitles. With subtitles, I eventually forget that I'm reading. With dubbed speech, it's like the audio isn't synced properly and it drives me nuts.

You can watch it in the original Portuguese with English subtitles or if you feeling lazy and don't want to deal with reading, you can watch it in dubbed English (just don't look at the mouths when the characters speak....  lol)

I highly recommend it and you won't be disappointed.
