Robert Downey Jr is a very busy man. He has a lot to uphold amongst his Hollywood comeback, first donning the Iron Man suit and now almost certainly entering a second franchise with one of fiction’s most beloved characters. It’s funny then that the character of Sherlock Holmes hasn’t been a favourite in cinema; the bumbling detective now has one of the most known falsely quoted lines in history. Sadly but rightly so, said line fails to actually be mentioned – but the 1800’s London setting gives Guy Ritchie the perfect opportunity to do what Guy Ritchie does best – show the gritty side of town with a bit of humour thrown in. More than a bit – this is his most family-friendly film to date. After all, it is a ‘blockbuster’.
