The biggest problem with this show is that it's just filler space for the Marvel movies, since they can't possibly reveal or mention upcoming big events that will be shown in the films. So they're just basically killing time until the next films are shown, while dealing with lame-ass bad guys like the Rising Tide and Centipede instead of biggies like Hydra.
I'm curious to see how this show will be affected by the events in
Captain America: The Winter Soldier, as it will reveal kinks in S.H.I.E.L.D.'s main organizational structure and some traitors within it. But the way this show is going, they'll just probably gather around at some touchscreen table and just talk, talk, talk. ....zzzzzzzzzzzzz
