Good but not great movie for most of the run, but boy do things fall apart at the end. They're all but told that they're free even after committing those extra robberies, and instead of thinking it would be a great time to pick up their chips from the table they decide to bet it all on Red 19.
Would a FEMA place like that even have all that money? Blink dies but then he's alive, magically not in jail and his graphic novel is a big hit? And then the mid-credits scene to top it off? Was a really strange and poor kind of wish fulfillment after-life bit that just feels entirely out of place with the rest of the movie, and him being alive isn't even close to believable but if they don't want you to draw your own conclusions from an ambiguous ending then I don't know what the point of all of that was, and if they did it was terribly executed.
