A lot of this criticism is by invitation: L&P is aiming for realism and refers to them self as a perfectionist who has to spend so much time because they can't compromise on quality, then naturally all of those minute details are up for scrutiny.
I guarantee you, if L&P announced that the Aiden event was completed in two weeks instead of five (six now?!!!) that would be applauded and met with raucous cheers. For this event the criticism is that so much time is spent building and composing and lighting and test rendering and camera adjusting for an incredibly complex environment (forest road) that cannot be reconciled with its importance to the story, while getting some details wrong as well.
It will surely be gob-smackingly beautiful, the whole event may even be really great - and by great I mean consistent with the characters and story as they were leading up to the event with ample naughtiness - but, in the context of the 30 playable days, it's impossible to imagine that it justifies five or six weeks of development.
