Good entertainment.
I like the plot of
'Blood Work'. I'm unsure if it would hold up if you went through with a fine-tooth comb, but it certainly gave me the required enjoyment levels. Clint Eastwood gives a sturdy performance, as do Jeff Daniels and Wanda De Jesus; elsewhere on the cast, neat to see Anjelica Huston and Rick Hoffman,
Louis Litt himself, appear in smaller roles.
It's not as unpredictable as it perhaps thinks it is, due to the casting more than anything, but I had a fun enough time with it.
