What a crap ending

I mean I could get over Blake Lively narrating the movie and the terrible acting from the lead actors, but the ending was so horrible that I couldn't get over it at all.
(Spoilers)
So Benicio takes the car and just escapes as if nothing when he is surrounded by Federal Agents on Helicopter? I am not even digging into the various moral ramifications that the ending leaves untouched. I am just talking about how silly the ending was. Its as if the writer and the director just went F&$k it.
I feel like Stone has lost his passion about making movie. I don' think he's made a great movie since Nixon. Its as if he were an athlete who is past his prime.
