Sherlock is such a well-presented game, obviously created with care and great attention to detail both graphically and plot-wise, that the problems end up sticking out like a dead man’s arm at a crime scene. I've already mentioned the voice-acting earlier, which in general is pretty good, but there are some actors who truly sound terrible and extraordinarily amateurish. It really lets the game down considering there are so many conversations and because the majority of the voices are really well done. One particular character had me cringing every time he appeared because of his stilted and horrendously weak delivery and some unintentional comedy is to be had from some hilariously bad cockney accents.
