That one with Alistair Sims, is a good Christmas Carol.
Sometimes a good movie (for a character study or a passion play)is one that appears natural, and is not over contrived, not over acted or excessively produced.
If the movie is meant purely to dazzle, entertain, shock and awe, that requires a different recipie. then sort of film becomes the creative plaything of a director, a petri dish of CGI experimentation, as with Star Wars films, Super Heroes, or something very gorey by Tarratino. I no longer see any Tarratino films. Way too bloody when it’s not even necessary.
I hate CGI and all of the garbage that they put in today's movies! Movie makers now assume that special effects are the ONLY "important" thing there is and so movies wind up being acted by actors who can't act and mumble, scripts that a 7th grader ( from when I was in that grade ) could have written better, car crashes, blood & gore, and gratuitous nudity and sex.
It's a very rare movie, indeed, made today, that I can watch and enjoy; unlike the many films from the '30s-'60s.
