I'll keep this review super short and explain why this collection deserves 4 and not 5 stars:The first 3-4 episodes are rough, and don't flow very well. There are some cliches and stereotypes that you find in a lot of TV cop dramas. A few scenes brought eye rolls, and made me think, "Hmm, I have a feeling the 'network' threw that bit in to make it more popular for the 'masses'." Thankfully those scenes disappeared after awhile; the episodes on the 3rd and 4th DVDs are superb and top-notch. The writing is much stronger and flows better, the cliches are gone, and the acting is strong throughout the series.
