So much TV is crap. So much "made for cable" TV is formulaic crap. This show is a cut above. While it doesn't entirely step out of TV "world 'o' crap", it largely sidesteps it with a real flair for brilliant hindsight in the retelling of some really interesting crimes from the 50's and 60's.
In the end it doesn't matter if it is the final word in honesty because it brings up so many unanswered questions pertinent to crimes that are, sadly, now forgotten. But do not take this lightly because these are major crimes and deserve, even at this late date, your introspection. I can't tell how important this series actually is so just watch because if you get it...you'll get it.
