One problem I had with the film was Hal's whole "you have to be chosen" exchange with Hammond.
We've seen this before: the villain has the hero's girl all telekinetically frozed up and shit, and has managed to get the hero's powers to be useless in order to save her. Now in control of the ring, Hammond blasts a hole in the wall behind him (something he could have done with his old powers, mind, raising the question of why getting the ring was such a big deal for him in the first place), and then turns the device on Hal. On his previous promise not to harm Hal or Carol, Hammond has this to say: "I lied."
But, before hitting Hal, Hammond's green energy bolt freezes in midair. "I lied, too," Hal says, as Hammond realizes that he's completely screwed at this point. Even without the source of his powers, the hero still has control over them over the morally inferior villain, probably due to the power of love or friendship or something. "You see, the way it works is..." This is it. Hal is about to lay the the movie's main message and theme on the villain, showing us where the two similar men's paths diverged. This is what separates the good from the evil in this universe, and it's what the movie wants us to take away and apply in our own lives.
"...you have to be chosen."
Pardon? This is the big moral summation of the film? Granted, Hal gets a much better one later on when he's with the Guardians before heading off to fight Parallax, but this is a major point in the film's plot, and we're expecting some sort of moral closure before Hal finishes off the primary villain. Especially since Hammond is so sympathetic (his dad's "doer" speech hits extremely hard to anybody who's felt that they don't live up to somebody's expectations), we're expecting some last "this is where you went wrong" speech, but all we get is "You have to be chosen."
So remember, kids, that no matter how hard you try or how many achievements you make, everybody (and that includes your father, your peers, the love of your life, and space aliens) will always, always love the handsome, cocky, thrill-loving "doer" more than they love you, because he's just naturally better. No getting around it, he was just born better.
