It’s incredibly difficult to assign a grade to SHIELD’s inaugural season. I’m sold on the show now, but I’d given up halfway through until I’d heard it improved and Captain America 2 confirmed something had to be happening. The first half is fairly awful, with boring characters and weak stand-alone plots, like rejected X-Files episodes. Then Winter Soldier forced a change (though clearly in the works all along), and the show becomes episodic and suspenseful, full of great reveals and red herrings. The characters found their places, and the actors meshed. Even the fight choreography got notably better. It attempts Whedon-esque wit throughout, and the quips evoke more chuckles than groans. The addition of some fantastic actors, including Bill Paxton and cameos from Sam Jackson, Patton Oswalt, and Cobie Smulders, also did much to improve the show.
