I wish I could compare fairly
I saw the 1944 version on TCM recently (Netflix doesn't have it!) and chased tonight with 1940. I really enjoy comparing versions of films/stories, and usually I'll give each the benefit of the doubt (although in the case of Dangerous Liasons/Cruel Intentions there was obviously no contest).
At any rate, I really wish I could have seen a cleaner print of Gaslight 1940. I really enjoyed 1944, and I would love to know if it's just because I have a crush on Bergman or if it was truly a superior film. Certain plot elements became clearer upon viewing 1940, and I must grant that each has its own merit. I just wish they were on comparable levels aesthetically, so I could be more objective (I have the same problem with the Japanese and Korean versions of [The] Ring, FWIW - production values vs. plot elements).
