It was a very sick movie with kids that find aliens or an alien ship in a grey landscape. Aliens with strange suits and I think that an alien kid was dying and they needed help,I don't know.I am not very sure about the plot.. It was very sad and the music was weird and sick. Not a very big production,that's for sure... Please help me,I don't know anywhere else to search...

Could have been mac and me or max and me
