One of the things that I like most about this series is that the premise - the work and life of the bike cops, who patrol Santa Monica beaches - is somehow new. I mean there are many crime shows, but how many of them deal with bike cops? As far as I know, apart from "Pacific blue", zero. I have seen around 15-20 episodes so far, from different seasons, and in my humble opinion the quality of this series diminishes with each season. In the third season there were changes in the cast, which I think made the show less interesting. The original cast was better than the actors, who replaced them (or maybe I were used to the original actors and had prejudices against their replacements). However, a few people of the original cast didn't left and because of them this programed was still watchable. So, if you like escapist, fun shows and you don't mind mostly impossible and sometimes silly plots (later seasons), it's almost certain that you will enjoy this show. The beautiful scenery, likable actors and actresses, competent cinematography, tame for a crime show violence (especially for today's standards) and sometimes excellent scripts make this show worth checking out. But, I have one suggestion - start with the first season.
