I am directing this question almost soley out Dewey, but I really enjoy Law and Order, Sam Waterstone, Jerry Orbach, Angie Harmon, Carey Lowell and Ben Bratt, I was looking on Amazon for DVDs but I could only find Seasons 1 and 2 which contain none of those characters.

Do you think its worthwhile purchasing them, they are only £15 or so, but I don't want to be dissappointed!
