Starts well, ends up a bit flat *spoilers*

I thought this movie was sharp as a tack right up until the point that Jack and Fay run off together. It started when the movie basically cut from them arriving to them already in the sack together. There seemed to be something missing there. Sure, I knew they'd probably end up sleeping together, but the "cut to: they are boning" was really abrupt and characterized how perfunctory the rest of the movie was.

Why did Fay roll over so quickly when Jack wanted to head off alone with the money? She was completely untrusting and manipulative, but she gave up easily here.

Suddenly, Fay and Vince are working together again to double-cross Jack. This also seemed abrupt. Obviously it needs to be a surprise for Jack and for the audience, but last time they saw each other she was braining him with a rock, and he didn't really seem like the forgiving type, but in no time at all they've apparently made up and formulated an entire plan.

And that ending. Vince and Fay just handily get blown up so that Jack can escape, as the cops will presumably think it was him in the car. This was incredibly convenient.

None of this would have mattered as much if the first two-thirds of the movie hadn't been so tightly plotted. I was really looking forward to a zinger ending that it seemed to be building to, but NOPE.
