Bumping this old thread to comment that I recently watched (for the first time) my Region 1 Blu of The Cell, after having it for a while.
I've only seen this a couple of times before (on the DVD), and have been impressed each time. If anything, the movie gets better with each subsequent re-watch. Amazing movie. Visually gorgeous, with an extremely unsettling/disturbing story - and excellent acting/casting.
The dream-like nightmarish landscapes/scenery & the horrific characters only added to the bizzarre/trippy nature of the film. I can honestly say that this film is in a class by itself, and that's an extreme compliment.
The PQ of this Blu wasn't that much better than the DVD (and maybe no better), but no surprises there - given the reviews of the R1 Blu I've read over the years. I'm still glad I got the Blu, given that I've never owned the DVD.
