Slightly worse than the original... but good

Rating: 7/10 (18 February 2020)

Even more full of action sequences that scream "big Hollywood production", this is not as good.
The actors are as efficient in their roles, even with the small changes the story has (Watson is about to get married and with that the duo adventures).
The plot takes us outside Great Britain at some point, and the movie takes a hit visually when we part ways with the Victorian period. Besides, more characters are presented (all "meh") and the scale of the story gets continental, which makes it a bit forced.
But all of this is in service of the villain of this story, the Professor Moriarty, and here is the biggest difference with the original. In the other, the villains were ok. But here, the superb Jared Harris gives his character a malicious presence that matches only his genius level intelligence, making the perfect Sherlock adversary. And yes, the plot gets too big and forced, but also ultra epic, and still perfectly told by Ritchie. Again with an amazing conclusion, it makes every 'boring' second in the other acts count. Also, visually and in dialogue, gets to an incredible level (with insightful but cynic words about the inevitability of War, and the conclusion of the battle of the minds between the two geniuses).
The especially bad of this movie was the sexist and criminal role for Rachel McAdams as Irene Adler, and the pathetic cast of Stephen Fry as Sherlock's brother, failing miserably in his "comic relief" role.
