Did you read the article?
Well I know what a strobe light is, so would not compare it to a typical strobe effect in intensity; but then I would not notice if I was not effected by it as some apparently are.
Still that being said, there was not "a graphic birthing scene". That is what I was hung up on as in the description of the "birthing scene" where in that timeframe of the film, the audience member hit the floor.
I guess we have beaten this dead horse to death. :)
