Blood Work has a faintly ludicrous premise - an ex FBI/Private Investigator has a heart transplant and after finding out that the donor was murdered is enlisted to track down the killer - but if you can swallow the concept this turns out to be an above average latter day Eastwood thriller. As with much of Eastwoods recent material however, this is a mixture of the excellent and the banal - for every decent plot-twist or piece of character observation, we have scenes that could come from any cheap TV thriller - the animosity between Eastwood and his ex-colleages, the way a Private Investigator can spot obvious clues the police miss (like having a lip-reader translate the killers dialogue from CCTV footage), and of course the grizzled Clint having his way with the leading lady. While I worked out where the plot was going long before it got there, the final twist of who the killer actually is is an excellent one - but unfortnately once revealed the charfacter turns out to be a one-dimensional cackling serial killer. Blood Work is an enjoyable if unspectacular thriller, and while an improvement on Eastwoods films immediately preceeding it, this is still a long way short of his best work in this genre.
