The thing that grabs me most at the end of the trailer isn't the ever present quipping or action shots, or the look who gets to meet who. Those are all fun sure.

No, it's that very brief cut of a (probably) young Gamora holding hands with her father. Guardians has always been about dysfunctional families and their love, abuse, isolation.

With Thanos as our headliner for this, undergirding his pseudophilosophical balancing of life and death nonsense through magic rocks with a real theme about his relationship with his children might give a touch of humanity to this shameless popcorn fest. Not that there's anything wrong with pure popcorn.
