You're kidding right? That movie had a defribulator that brought Bond back to life seconds after it shocked him. That's so far away from how defribulators really work it's ridiculous. Not only that but he walked right back in. He'd have had burns on his chest and most likely major breathing difficulties due to the pressure placed on his chest by the shock.
Having said that I did enjoy Casino Royale, a lot more than any other Bond movie I've seen (I can't sit through one from start to finish they bore the crap out of me), so I'm looking forward somewhat to this next installment if they keep on the same route.
