Thought that I should update this.
I did get one and used a free 14 day sky movies trial and then brought 2 months of movies in the black Friday deal for £5. And still have the 2 month pass that came in the box.
My verdict is that the interface is very smooth and quick to load when compared to my smart tv and iplayer on my bluray player, we only really got it for the catchups so the movies are a bonus, the quality of the stream is pretty good even on my 55 incher but what lets it down is that it is not in surround sound, also once that you have had a good bindge on the movies we struggle to find anything we want to watch, so I think the best option is to only pay for the movies every 4 months or so and watch all the good stuff that has been dripped on in that time all in one go.
