same as finding out that Tom Cruise is a wack-job hard-core Scientologist. I still like Tom Cruise movies... but knowing that about him just erodes my appreciation of him.
When you watch Jack Ryan or Ethan Hunt, are you thinking about them undergoing auditing? While he is in the role, I don't think about it, but it might influence my decision to watch something. I did like House of Cards, and watched the first couple of seasons but I have yet to borrow the DVDs for the following ones after the how Kevin Spacey debacle.
