CSI : Blood Drops
24 September 2014 | by (United States) – See all my reviews

Blood Drops is considered by CSI-philes to be one of the show's first masterpieces and at the top of the list for best episodes ever. There are a lot of episodes, though, since Blood Drops premiered on television in CBS. It is quite brilliant…and disturbing, to say the least. The unsettling crime scene of a family's murder opens the episode as police are unable to hold their lunch as even Grissom finds himself having a hard time stomaching all the blood and viscera. A blood circle sign is placed in rooms of the house (walls and mirrors) around each murder. Only the two "sisters" (a key revelation explains their relation which adds an extra gulp in the throat as to why the murders happened) survived this and why they did is part of the mystery that Grissom and his CSI team will need to uncover. Other subplots include Eddie, proving to be just the kind of scumbag he is, pretends to be affectionate to ex-wife Catherine only to turn her into Social Services by filing a "neglect parent" complaint citing her job as being considered more important than the child & Day Shift CSI head, Eckle (Mark Vann; later to be a more substantial and multi-dimensional character than represented here), doesn't shy away from challenging Grissom's leadership abilities against his own regarding handling the press (and co-operating with the sheriff who expects to be informed on case developments). Grissom's angst with Eckle will continue and his volatile relationship with Sheriff Mobley (Glenn Morshower) over performing duties as a CSI head through communicating the process and details of his case as developments arise. Competing with Eckle is cumbersome to Grissom because he is all about evidence leading to the case solved and the emphasis on revealing details before he's done is a burden. Eckle clearly attempts to provoke Grissom's anger by "monitoring" his evidence without his permission (dayshift and nightshift are to avoid each other's cases). Dakota Fanning has an early appearance as a child who had suffered a severe trauma and her only word "Buffalo" speaks volumes as to why the murders happened. Tina's (Allison Lange) secretive nature and apprehensiveness during interrogations soon unveil a horrifying truth. The studious, intricate investigative techniques of Catherine and Grissom turn up some remarkable finds; particularly Catherine eyeing a big drop of blood that answers a specific question regarding the location of the father's body in the house. Sarah Sidle is assigned to tag along with Fanning's little girl and make sure she sticks with her during her processing and evaluation. Sarah doesn't like the idea of this, at first, but realizes the importance of providing this girl support and be a source of comfort (the girl even trusts her in performing a body scan which will tell a great deal) during the whole ordeal.
