*SPOILER ALERT* I really enjoyed the early Holmes series but this presentation was for me an unmitigated disaster. The cast worked hard enough but I am surprised that Moffat and Co. decided to take Freddie Kruger to Disneyland for a campy farcical romp. Set ostensibly in two time periods Sherlock's mystically brilliant but ridiculously bloated pudding of a brother says 'a virus in the data' whilst we are in Victorian London during Sherlock's drug-induced mental time travel trip. Notwithstanding my Kruger in Disneyland comment this was more a mixture of a Brian Rix farce and a poor Dr. Who episode (or Harry Potter on an LSD trip) than a serious attempt to continue the series in its original entertaining and thoroughly engaging format. Bluntly, if the future episodes follow this Gothic nonsensical format it's a series I will not be watching in the future. I am however clinging to the hope that this episode was presented as a purposely whacky new years piece of 'entertainment' for minds that were already in something of an alcohol induced debilitated state. Time will tell. I give it 3 stars because the inland navigators (or navvys - i.e. actors) did their jobs well but unfortunately the railroad tracks were laid (courtesy of the writers) in entirely the wrong direction and ended up in the middle of nowhere. Very forgettable.
