I can understand the feelings of ickiness surrounding the topic, but I have found both the incident and the series to be extremely interesting and pretty damn compelling. The idea that Pam, Tommy and the PI all thought they could get this video back and that would be the end of it is fascinating to me, and I was a grown man when the tape was released out in the wild. This may have been the first known incident of revenge porn, when it became clear due to the emerging interwebs that images and videos of a salacious nature can never be recovered.
Blaming the miscarriage on the stress of the tape release is interesting, but I don't have a problem with shows based on a true story mucking up the timeline to add dramatic poignancy to events, so long as the events that are depicted actually happened.
