This second OAV series is an extension of the 47 episodes TV series, and should be watched after it. In the TV series, a lot more focus were put into the mecha, there were (a few) more action scenes ; more plotline about the development of new models of Labors, and about the SV2's missions with their Labors. All these plot elements were concluded in the last episode, without anything spectacular but still satisfying. Of course if you expect Patlabor to be a heavy political/action show, you will be disappointed. From the begining, the Patalabor animated series was about policemen being blocked in the godforesaken hole of Tokyo, wainting for some mission that ended up to be "arresting drunk guy that seized a Labor to do something stupid". The TV series already exploited that to the end, so here you'll get Patlabor mostly without mechas. The more this OVA series progresses, the less there is mecha action. The writers just wrapped up quickly the action arc known as "Griffon arc", still leaving some unresolved elements (a way to say that, even after the end of the series, the SV2 will continue their job and there will still have criminals to arrest) to go for the core of Patlabor : the bunch of various young misfits that compose the Special Vehicules Unit 2. It will go from completely comedic episodes (I found them hilarious), then, when you expect it the least, BANG! A serious episode about some members of the squad that gets awesomely intimist. Yeah, because Patlabor gets very intimistic when it wants, getting really into the character's life and all. But even in simple comedic episodes, there is still a way to show the character's personnallity, they always stays appealing despite their flaws. Those guys are average guys, which is rare in japanesse animation! They don't suddenly have specific abilities, what they can do comes from past experiences. If one is good with computer, it's because he was in informatics beforehand, for example, and never any of their character traits feels exagerated or forced, even when it is used for comedy. This is what makes them seem more humain.
This was the writers last show before the end, so they ensured to have fun, but they never forgot to let their characters shine. Some of them doesn't feel like they were exploited enough and that's a shame, but they still had at least one moment during the whole series, whether it would be during the TV part or this part. It has it's flaws of course, but I can't put the finger on it, beside the fact that I felt a lot more could have being done. But at one point, it has to end. After that, the Patabor franchise would "end" on Patlabor 2, which didn't gave enough time to show a glipse of the charactes some years laters... Well, in an another continuity (the third movie being a spin-off, and even taking place before the second movie, can't count as an "end"). This extension of the TV series is a goodbye, to those idiots working more efficiently than they seem, sometimes immature, sometimes desctructive, but full of wisdom and courage. Personnally, I'll miss them.
