Started off promisingly but by the middle of Episode 4, I really wasn't bothered about the lead characters... for the life of me, I could not understand why the irrational sad sack just handed over the money and then thought it was better to jump off a moving train to retrieve the money!
The show also failed to explain why Alice/Fiona deleted Ruby's "Run" message in one flashback.
I also struggled to understand why despite having a sack load of cash, they didn't bother getting a change of clothes or even underwear.
The ending was ok as it left scope for a second series but should they bother?! I think not.
