Earlier quoted context omitted.
Is that because you don't trust yourself not to watch it all in a binge situation? The shows on netflix could easily be watched one episode at a time on a regular schedule if that's what you prefer. You get both options (and hundreds of other scenarios) instead of just the one decided by someone else (or else having to record it on a DVR to make your own schedule).
It's nice to know that the other people watching a show are also at the same point as you are (or relatively close), allowing you to speculate on what might happen next in the time between episodes. I also like looking forward to the next episode, which doesn't really happen when you can watch that next episode immediately (and self imposed waiting doesn't feel the same).
The shared cultural experience is nice, but utterly foreign to those of us outside the US, where the discussion arrives weeks, months, or even years before the show.
