Ending: Good Idea, Mediocre Execution

I actually was thoroughly invested in all three acts of this movie. Gosling's was the best, but Cooper's arc definitely was enough to carry the rest of the movie. The fall-out and eventual mending of he and his son's relationship was something of beauty. Even more effective was Cooper's grappling with how honest to be with his job; and I was not expecting the twist with Ray Liotta's corruption, actually. I like all these parts the more I think of them.

But it was the very last scene that just didn't work for me. I get it, Jason looks for his dad's motorcycle to get his inheritance and... that's it. I literally didn't have any kind of emotion, despite the exhilaration I felt when he met up with Robin and that song from the trailers kicked in again (in some ways I feel he should have gotten the motorcycle there and ended with the confrontation between him and Avery). And when he was caught in a robbery like his father, I got chills. It was all coming full circle until everyone's life just goes on. It was setting up a Greek tragedy until they said "the hell with it." It would be like if Breaking Bad ended with Walt and Jessie just walking around in Alaska doing nothing; no come-uppance, no major changes except a renewal in Avery's and AJ's closeness. Am I supposed to feel this... empty at the end of what was such an ambitious film up until that point?

If I'm missing something, please let me know. I'd be curious to hear what everyone likes about the ending if they do. Still a really good movie, a solid 8/10, but it was approaching masterpiece status until the ending petered out and made the whole movie just seem like "well, that happened."
