It was a largely disappointing ending. The point seems to have been that the Steve Mackintosh character (the manager of the cash depot) wasn't really interested in stealing the money - he just wanted to get the feeling of power and invincibility back, as he'd 'been afraid' for most of his adult life.
You see Marcus and his wife driving off down a motorway and hear him saying, "I've got an idea...it's a really good idea this time..."
Chris at the end was safe, and I assume his character will remain safe, but then there was the question of the information he gave to the police - how would that pan out for him during the subsequent trial?
All in all, it needed one more episode to tie up the loose ends.
A bit frustrating.
