The best TV drama of the year imo, over the moon this is getting a steelbook.
Might be worth waiting for reviews of UK release before shelling out again for replacement 24fps discs.
Just because the UK discs are 1080i 25fps doesn't necessarily mean their inferior, it all depends at what frame rate it was originally shot at.
The US release was always going to be 24fps because most blu-ray players aren't equipped to play 25fps discs.
The reviews of Dekalog (The Criterion Collection US 24fps) and Dekalog (Arrow UK 24fps) over at the other forum is a perfect example.
The picture quality of both was deemed to be very good but only Arrow's release was playing at the correct speed due to Criterion having to adjust the frame rate for compatibility in US.
All that been said I hazard a guess that most wouldn't be able to tell the difference and any blu-ray release will superior to SKY/HBO satellite/streaming service
