It's the kind of thematic resonance that was missing from the last two episodes and helps to provide a bit more gravity without overtly sacrificing the family-friendliness.
Agents of S.H.I.E.L.D. is a throwback to the action/adventure shows that I grew up with. Shows like Buck Rogers, the A-Team, The Six Million Dollar Man, or Knight Rider even.
The first step on the road to The Avengers was taken in 2006, as actor/director Jon Favreau was hired to direct Marvel's first independent production, Iron Man.
This time around, though there were punches, new tech, new super-heroes, spectacular revelations about the deceased Howard Stark and a development in the relationship between two of the main characters, Tony Stark and Pepper Potts, I did not jump on my seat at the end of the movie.
