Hmm...I think Alex is on board with a lot. He is resistant to a lot, it seems. As far as the marketing of the relationship, he is on board, I think, but again he only goes so far. The fact that he won't speak has done more damage to the marketability and to KB than anything. Also, there is the issue of PDA or just taking a picture together. All of KB's last relationships were full of it. Cameras or no. As a marketing strategy, it works. Again he is resistant to it. Whether it is an issue of support or not re the Nylon party. I think he has backed himself in a corner there because what else could he do? There were probably 8 people there. (Coincidentally some of the from Straw Dogs.) We don't know if it was a private party for certain. At least I don't. I just know what the captions on the pictures said, what JJ said, and what RB...er...the LA Times tried to cover up. Alex as a man has been getting ripped by many women (his base audience) for letting KB take these hits, walking in front of her, ignoring in public, etc...We already know that there have been a huge amount of PR corrections. Seems like everything we say is corrected. So again, what else could he do. Either way, boyfriend or PR strategy, he had to be there. That area is to murky for me to make a concrete decision yet, re his support or his job.
As for Straw Dogs. This was a bad strategy. We have been saturated with them as a couple. The line has been blurred from them as actors and them as a couple. A lot of people are going to be looking for the chemistry that is non-existent in the few pictures we have of them together. While looking for that chemistry, it is going to take the focus off the acting and onto Alex and KB. So then, when you get to the rape scene (which is appallingly horrific) all I would see is Alex rapping his girlfriend. That to me is completely repugnant. They tried too hard to push the KB/AS love story and they deliberately caused questions and examinations with the are they/aren't they stuff. So now the focus won't be on the movie. It will be on them. This was a stupid strategy. Acting or no, that is just vile. That is supposed to be his girl.
To add: This is my OPINION
