ABC's unwieldily named "Marvel's Agents of S.H.I.E.L.D." debuted in the fall with really strong ratings, but it quickly sank to the ranks of mediocrity - and deservedly so. Most of the lead characters were boring, and the show fell into a rote dangerous villain of the week pattern. There was some head bad guy named The Clairvoyant, and some recurring dudes with metallic centipede-like things on their forearms, but it was mostly boring. Not so boring that I stopped watching, but it certainly seemed disappointing compared to the high expectations that it had generated.
Then came the episodes that bracketed the debut of "Captain America 2: The Winter Soldier" in the movie theater, and the show quickly picked up. But is it too late?
