I've been wanting to get this on blu-ray for a while now but it was always in the £15-16 price range.
If you have a walkers code, you can get this for the said price of £8.86. If you do not, you can buy it from Amazon for £8.99.
I think the best news is that it's actually a really fantastic remake of NGE. All the action and plot with a little less of the metaphoric nonsense which made the original quite difficult to watch.
