There are lots. I think as Actors the paucity of quality films, scripts, lack of originality and the fact many don't have to develop the skills the way the older generation of actors did. The social backdrop of instant celebrity also means we view many as disposable and i for one couldn't really give a shit for most of them or their films, I just don't feel invested in them or the films like i once did, perhaps more a reflection on me - sad really.
