I've said this on every Netflix post I've come across, the multiple part binge is THE WORST option.
Either all at once for the full binge, or week to week for weekly discussions. You can tweak it a little and do the week to week with binges, usually the multiple episode premiere, sometimes the multiple part finale, sometimes multiple episodes each week (although you hopefully keep it consistent, e.g. two episodes every week).
The random multiple part binge means I am absolutely waiting until the entire series is out and when I'm waiting I don't really care when I watch it. I might watch it immediately, or I might watch it a month from now. Since Netflix makes their decisions based on "opening weekend", most shows are going to fail.
