I have it. Didn't do a direct A/B to the Criterion but I imagine it is quite an improvement. Don't go into it expecting your socks to blow off- there's still a ton of grain, a little EE and it's kind of dark. Unfortunately this film may never look a whole lot better without an expensive restoration it will probably never get. The soundtrack is the same- better, but still thin and hollow sounding. The extras are nice, especially the episode of "The Directors" featuring TG.
I plan to keep my Criterion Edition for the commentaries but at probably $13 or so the Anchor Bay version is well worth it.
