The writers struggle to update classic Holmes.. again. So taking the "I'm bored Watson" theme where Holmes laments the lack of crimes to solve (from the police, runners, walk-in's or the papers) trait worked will in literature but transplanted to modern NYC with radio scanners, internet, 24 hour news and we are supposed to believe that Holmes had nothing to work on? Dear Lord this is weak sauce.
So this week Holmes randomly picks a plane crash that just happens to have murders where right from the start he spots a murder due to lack of blood (despite there being zero blood anywhere at all and therefore disproving his point even as he makes it). Holmes painfully narrates a blackbox for no apparent reason before a murder-board of photos with no blood in them.
Next we get some of the most insulting detective work put on TV. Holmes takes out a memory card from a damaged phone and amazes the police that you can get voice mail off it.. That makes no sense at all.. none.. zero.. zip! But there's more.. next Holmes gets hold of a stated "cheap" CCTV tape that was apparently a high-def TV camera with massive resolution that has clear detail of 1cm high lettering from 30 feet away and Watson wants to know if he could enhance it. What! Eh? the best part.. it serves no useful purpose to the plot and is never mentioned again.
Sherlock's dad scene was painfully obvious and even more insultingly they seem to have decided to start parodying House's glockenspiel music motif. At least they didn't drag it out and ended it pretty quickly, presumably hoping that the brain dead audience wouldn't have time to figure it out. Sadly the rearranged time of the meal earlier on hinted at this conceit and actually ruined any attempt at a surprise almost by accident it seems.
Holmes further ignores reality by having aviation fuel soaked sand as a timed delivery for a surefire plane crash, lets not even insult the audience by discussing the plot holes here.
Finally Holmes confronts a suspect who shows more knowledge than he should have and has a terrible alibi that Holmes just accepts. Then sin of sins they resort to the "The plant that only grows in one place on the planet" plot.. bugger me could they be any lazier and lets not forget the stupidest hiding place for illicit cash.
Just to give Sherlock something to do they contrive a scene where he suspects a man in custody has a serious wound so they wait an hour while he drinks lots of water to prove it, what! The man is a suspect in custody and even Sherlock has to admit they could just ask him to lift his shirt. The broken logic of these scenes are so weighty that the writers can't even make the scene work, just to give Sherlock the appearance of being clever but withstand not even the slightest examination.
The biggest problem this episode has that it highlights that there is no useful relationship between Holmes and Watson.. she rarely helps him, even by accident nor is she a sounding board for his work and as far as I can recall she's done nothing for his, now non-existent, addition problems since episode 2. She finally shows a thinnest of sleuthing abilities and gets a a verbal crowbar to get something personal out of Holmes, but even the language is awkward "I know about Irene. I want you to tell me about her".. so does she know or not? What she actually means is "I have something on you... now talk to me about your mysterious that's about as hamfisted as it gets.
