Agents of S.H.I.E.L.D. season two has been a high-energy experience, progressing from jaw-dropper to jaw-dropper, deepening its characters, and having fun with the complexity that the Marvel Cinematic Universe naturally generates. Where we are by its mid-season finale, “What They Become,” feels far more mature than where we were in the season premiere “Shadows,” and that’s quite a trick to pull off in only ten episodes.
It’s thanks to the consistent quality of these episodes that “What They Become” can be forgiven for being so. very. boring. The mid-season finale certainly had some exciting moments and developments, but they were a puzzling exception to an episode that, despite a lot of fighting and interpersonal drama, came off flat.
