Having spent a couple hours with Bride of Frankenstein last night where, instead of just appreciating the movie (which I had never seen before) I couldn't help compare the 4k with the blu. I have both movies ripped and could easily switch back and forth and I would watch a scene or two on one...
I think this movie is a classic and well deserved as a Criterion release, but apart from the potential benefits of HDR (which we didn't get), it's not worthy of a 4k release (when they've already released a great version). I'm guessing this was planned with HDR but when they couldn't get...
I compared this new 4k with my Criterion bluray. I could not detect any difference between the two (in my projection setup). I feel this purchase was a waste of money.
