I think that you will be pleasantly surprised with the great quality of the "TCM Spotlight: Charlie Chan Collection." The crispness and clarity of the four films in the box set was a joy for me to behold, especially when compared to what I had had available regarding these movies in the past.
I agree with your praise of the Poirot episodes. I also feel that this would be the only workable way to make any "new" Charlie Chan mysteries in the future. In my humble opinion, the Poirot series captures the feel of the era as well as the character in a way that Hollywood today would never be able to do.
