Watched the first four chapters of the Judex serial last night. Since it's a 12-parter, things move a little slowly (Judex himself doesn't appear in the Prologue). Also, so far no "origin of Judex." We don't know who is or where he came for, just that he is "a champion of justice." I guess this will all come out in the remaining installments. By the way, the chapters were presented in their proper order: Prologue, Chapters 1, 2, and 3. Hopefully, the later ones will be also.
