To many or most people, the 1951 version is so familiar that it is a bit of a shock to see a different, but equally valid, version. The Sim version is still the definitive one I feel, but ...
The Sim Scrooge is utterly plausible much of the time, but then he will be as giddy as a schoolboy, for example, giving an interpretation that an incorrigible naysayer could choose to quibble about. My reaction to Seymour Hicks was similar but, strangely, in alternation with Sim -- oh, he's better than Sim here, worse than Sim here, more realistic here, less realistic here. Any given scene with Hicks could be better, worse, or just plain different from the corresponding scene with Sim. This is partly what made seeing this version so enjoyable; you really couldn't second-guess the next scene.
There are significant differences in the portrayal of the ghosts. I think we are all familiar with Michael Hordern's eerie and frightening ghost of Jacob Marley, shrouded in chains, from 1951. In this version, Marley's ghost is invisible!! You hear the chains but you see nothing whatsoever. The Ghosts of Christmas Past and Future are also quite non-corporeal. Only the Ghost of Christmas Present is someone we recognize from Sim.
Tiny Tim is quite different. We expect Tiny Tim to be an eternal optimist, irrepressibly cheerful. But the Sim Tim (boy, I loved typing that) seems to overdo it a little. He appears to be "on something", to use the vernacular. In this version, Tim is toned down. In some ways, it's an improvement. In the Sim version, to its credit, there is a special balance however, namely, the repentant Scrooge has an exuberance which matches Tim's precisely, and they appear together in the final shot, as we all know. A perfect ending. Back to that later. A key difference in Hicks: at the tragic moment, we do not see the lonely crutch we're used to; oh no, we see Tiny Tim lying dead!!
This version has some scenes which are not in Sim. This version in general has more singing, and one of the extra scenes involves the Lord Mayor of London giving his Christmas toast to Victoria followed by the singing of God Save The Queen.
In Sim, Scrooge comes to his senses on Christmas Day and there is a warm and funny scene with Mrs. Dilber, the housekeeper. Not here. Here there is an extended scene of Scrooge and the prize turkey! Scrooge goes to the butcher shop which is closed, snow falls on Scrooge, Scrooge throws snow, snow hits butcher. Butcher opens up, Scrooge orders turkey, Scrooge goes home. Scrooge gets dressed, boy brings butcher, Scrooge still dressing, butcher tries to leave with huge turkey, Scrooge answers door. Scrooge then pays the butcher, pays the boy, and gives the boy extra money so the boy can take the turkey to Bob Cratchit's house in a cab! Scrooge then leaves the house whereupon he meets the two gentlemen who were soliciting for the poor earlier in the film and volunteers to give them 100 pounds!
So, how does the film end? There's nothing about rushing right out to buy a new coal scuttle. No mention of scuttles in this film. It's Boxing Day and Scrooge gives Bob the day off. Then Scrooge joins Cratchit in church (!) for the singing of Hark the Herald Angels Sing. The End, with Tiny Tim not to be seen anywhere. So perhaps it's the warm emphasis on Tim that really clinches the 1951 version.
There are many moments of surprise and enjoyment here if the opportunity should ever present itself.
