All of these actors have brought there own "thing" to the character we all know and love. So of course, there is some dispute of how he would/should act. The actors are going to put some of their own personality into their characters and not everybody is going to like it. We, being the audience, also are individuals with our own ideas of how we picture "Sherlock" each and every one of these actors had their haters.
In context to this movie, Sherlock Holmes was portrayed by Robert Downey Jr. who, played Sherlock the way I pictures him from just the stories alone. But, the critics say that he was too violent, too sarcastic, and too snarky.
