This is very important. if you enjoyed this series, stop here. seriously stop. reviews here have combed the plot to within an inch of its life.
if you have no knowledge of UK courtrooms, like me (i have no idea if the complaints in other reviews about court procedures hold water) and decided to excuse stupid actions to human failings then you can enjoy this immensely.
i don't know if i'm trying to excuse plot holes here or if the writers meant for his characters to make seemingly stupid decisions deliberately. ppl do insane things everyday. look around you, reality is illogical.
at least everyone can agree David Tennant killed it here and the last episode made it worthwhile. the last 10 min were nerve wreaking. my heart was beating so hard, i couldn't breathe or move i could only stare mouthing "wow"
