Hello! It's hard to believe, but in 2010-2017 this whole series passed me by. I first watched it in 2023 and mistakenly started with the pilot episode. That is, I am the only person who got to know Sherlock from the pilot, and not from the broadcast versions.
I really liked the pilot. Deduction, modern details like telephones, young actors, unlike the elderly Holmes and Watson familiar from other film adaptations of ACD books - I really liked all this, and I continued to watch the series with pleasure.
I watched the broadcast version of Study in Pink in full only after season 4. Undoubtedly, technically SiP is made much better. It is a gift of fate that the first series had to be reshot, because the authors saw and corrected their shortcomings. However, the script is more harmonious in the UP. I consider the late insertions - the press conference, John and Mycroft's dialogue, the taxi chase, the drug bust - successful on their own but rather unnaturally inserted into the context of the first episode.
Sherlock in the UP is completely different - smiling, charming and calm. However, his appearance is less attractive. Although he is wearing the same coat, shaggy hair and jeans exclude the idea of impeccable style, which is inherent in his on-air episodes. The camera does not try to choose the most advantageous angle for BC's face, as we see it in the series itself.
However, I like both versions of Sherlock - the pilot and the broadcast one. It is a joy to see the very young Martin and Benedict in their roles. I do like one little moment at the very end, when they leave for dinner, Mrs. Hudson shouts something after them, and John answers, barely holding back laughter, it turned out very sincerely.
