This has been, for more than a decade now, my favorite show on television. The stories are powerful and they stick with you. Mariska Hargitay and Chris Meloni are the heart of this show. I honestly don't think the show would do as well without them. I would, however, like to see more of Munch and Fin. They seem to have sort of dropped into the background and are only in a few scenes of each episode. I remember earlier seasons when there would be an episode or two (or more) when they were the central characters.
The addition of Christine Lahti for the first few episodes was great. I wasn't sure if I was going to like her, but I was pleasantly surprised. I'm glad she didn't stick around for the entire season though. It was great to see Stephanie March back for several episodes. I wish she was back for good, but the way in which she was written out this time (unlike last time when she was put into the witness protection program) was very well done. Overall, this is definitely one of my favorite seasons of the show.
Also, even though the price is (or was...not sure if the current price is what it originally was) a little high, at least the season was released fairly quickly after the season aired on TV. I remember when the show first went on DVD, it wasn't until the 5th season was aired. And even then season 1 wasn't released first. So I'm just glad that NBC/Universal is releasing the seasons like nearly every other show.
