Well, I hope it is not just my imagination but that improved quality certainly seems to have been in general carried over to this most recent release. Whilst there are still the odd differences between the episodes, with The Jungle being just a little dark, the overall standard of sharpness and detail is very good. Even the slightly darkish nature of The Jungle does not exactly result in anything significant in the way of lost detail. Certainly the definition continues at the high standard set by its immediate predecessors. Shadow detail remains generally good, with just the odd lapse here and there.
Clarity is generally good throughout with just the odd evidence of grain.
There does not appear to be any real issues with low level noise in the transfers. Overall, the quality of the black and white here is good, with all barring The 7th Is Made Up Of Phantoms showing decent depth to the tones. The quality of The Jungle is better than decent and shows really solid depth to the blacks. The overall feel of all episodes is very acceptable with nice gradation across the grey scales, and there is nothing here that I could find the least bit objectionable. There did not appear to be any significant MPEG artefacts in the transfer.
