ABC finally took put together a better “series finale” trailer for Marvel’s Agents of SHIELD. It includes the short clip from last week but also has an extended introduction that highlights some key moments from some of the current cast. It’s a nice touch. It’s difficult to believe that the finale is upon us: the show had such an erratic schedule for the last few seasons and had its final season announced some time ago. But it’s here. The effects look great. And I’m hopeful for seven seasons’ worth of full circles.
