Marvel has unleashed a new trailer for Agents Of SHIELD season fur highlighting the arrival of Gabriel Luna as the Robbie Reyes version of Ghost Rider. Sadly there are no shots of his flaming skull yet, but we get lots of shots of his car in flames and looking suitably demonic. The season premieres on 20 September in States and will turn up –eventually – on E4 in the UK. With the move to a new later time slot in the States – the show will now air at 10pm – this feels like a make-or-break season for the show, which has always performed solidly but not spectacularly in the ratings. Does the inclusion of Ghost Rider indicate a new harder, darker edge?
