Season 6 of 'Law and Order' was a bit of an up and down one. Curtis didn't settle straightaway (understandably) and neither did his and Briscoe's chemistry (also understandable), though it was a case of them being fine in some episodes and regressed in others. It was more though to do with the quality of the episodes, there were some fantastic ones but also a few disappointments. None were misfires though and even the weakest episodes showed good intentions.
The topic in "Deceit" is a very controversial one, it was back then and it still is (perhaps even more so). The execution could have gone either way. It could have been dark and intense and also moving and sensitive, so quite emotionally layered as well as thoughtful. Or it could have been heavy handed and too judgemental, it is very easy to take sides on this topic (as is the case with a lot of controversial topics) with strong opinions on both sides. "Deceit" is a very good episode that is an example of the former on the whole in its approach to the topic.
"Deceit" has a lot to like. As usual for 'Law and Order' and its spin offs, the production values are solid and the intimacy of the photography doesn't get static or too filmed play-like. The music when used is not too over-emphatic and has a melancholic edge that is quite haunting. The direction is sympathetic enough while also taut. The acting is a major plus, with Peter Reigert giving a riveting, hauntingly tortured turn and an excellent one from Mary Beth Hurt. All the regulars are without complaint.
Moreover the script is smart and thoughtful that is very careful, but not too much so, at not taking sides. The story is compelling and explores an issue that can be very sensitive ground with tact and no sense of judgement on either side. The policing is entertaining, intriguing and not too routine and the legal scenes as to be expected provoke a lot of thought.
However, for my liking the ending is rather rushed from trying to cram in too much in a short space of time (same with the previous episode).
Will agree too that everything with the Miranda warning was sloppy, uncharacteristically so on the whole for this point of the show.
All in all, very well done. 8/10
