This article is from the NYPD Blue FAQ, by Dave Chapman, Alan Sepinwall and Jeff Knapp with numerous contributions by others.
Alan Sepinwall used to write a detailed summary/review of
every single new episode of the show, which were posted to the
newsgroup and archived on the website. However, due to time
constraints brought upon by home and work, he has retired from
that role. All the summaries he's already written (which
includes half of season one, all of seasons two, three and
four, and the premiere of season five) will continue to be
available on the website.
Update: Alan can't get rid of zat pesky summary bug. He has
still been doing reviews and such, tho the level of detail has
lessened a bit since he became Alan Sepinwall, cub reporter.
Happily, others in the group have picked up the detail slack,
most notably Amanda Puedo. You can catch her reviews by
checking for posts titled "Thoughts on..." Old reviews can be
found by searching thru DejaNews.
