I'll try, I didn't understand everthing because french isn't my first language either, I never speak it but I learned it in school LOL:
guy: we've visited his house,
piece by piece, photo by photo (and he saw a lot of other stuff which I didn't understand, I think he saw Michaels shoes but that would be weird
LOL)
girl: it was the best moment of my life
narrator: Michael Jackson is always surrounded by children and ????( I think adolescents). Just like here, when he celebrates his birthday in Neverland. (bataille the nourriture means food fight, they are all scream 'food fight!')
guy: In the real life, he's ... how do I have to explain it .... A four year old kid. ( I don't understand a lot now but he gives a lot of examples why he calles him 'a four year old child' I did get the last bit, he said:'playing on the flour, balance stuff on his head, watch videos, that's really just the child in Michael')
narrator: Michael Jackson becomes more and more deconnected with reality and the world of the grown ups, in Neverland but also outside.
The end!!!
LOL, I hope someone will give you a better translation , someone who speaks better french and english than me. I tried
