But Jensen never complained about challenges before. it takes something bigger than just feeling uncomfortable to voice your feelings like that. I just can't see Jensen deciding to complain just because he felt uncomfortable, he likes challenges he admitted that before. And to be honest that clarification for me sounded like a damage control :)
But i agree we don't know how he really felt giving that interview and we'll never know. I think fans interpretating his words in him being unhappy speaks volumes though. Fans projecting what they felt about the show and Dean's role and it tells me that big amount of fans aren't happy with the show this season.
