maybe i should instead to put 'Sign of Three' as my least ftavourite, switching place with 'The Blind Banker', though the latter has so silly carton like bad guys and deserve to be at the last place.
i watched 'The Blind Banker' again, and like the first half basically, but cannot get over the carton chars from the plot...
as to 'Sign of Three', i felt really betrayed by the show which is supposed to show how clever and super intelligent Sherlock is, even in a wedding or normal situation, but the writers seems to rather portrait him to be as silly as ordinary people, and get stupidly drunk and cannot even think clearly about the case and resolve it until the last minute. i almost feel like Sherlock is no longer the one and only Sherlock we know but a different person. i watched it a few times, but every time i felt the same about this episode.
the point is that what we like about Sherlock is because he's superior than all of us in intelligence and attention to details and deductions, and he's not an ordinary person like the rest of us. but this season, we start to see so many weaknesses on Sherlock side, especially in 'The Last Vow', when he's over matched by his opponent, and yet keep making mistakes till he's cornered to the last moment when he became a shocking killer instead. it really felt Sherlock is going down from now on, and we start missing the good old Sherlock in series 1 & 2...
i really hope they'd make up to us on Sherlock in series 4 to erase some of those silliness and judging mistakes from Sherlock in this series and get back on solving crimes and deductions that Sherlock is good at... or else i for one will be utterly disappointed and stop watching it.
