Active Raid follows a police unit in near-future Japan that uses personal robotic suits called Willwear. They're basically miniature mecha, taking on threats that largely come from misuse of technology.
Active Raid caught my eye primarily because it was broadly in the police/military genre, which I enjoy (one of the many reasons I'm a Ghost in the Shell fan). There are quite a few plot points that revolve around bureaucratic in-fighting, a staple of the genre. The unit members fit broadly into the usual stereotypes: techie handyman, calm but rule-bound fighter, info hacker, hot-headed fighter, and so on. The overall story progresses from seemingly unrelated crimes to tracking down a shadowy mastermind (twice, since it's broken into two seasons). I'd say the series does an adequate job of representing the genre, though nothing particularly new or exciting.
At first glance, Active Raid does very little to make it stand out from any similar series. A bunch of young officers are gathered in a special unit that takes on mecha...I mean, Willwear...threats. Just about every episode makes sure to spend time going through the Willwear-equipping process, making it look like a toy commercial. The villains are caricatures, from bank robbers to love-crazed idol fans. Fan service is minimal as far as these kind of series go, but certainly not completely absent. Not exactly breaking new ground.
That impression never completely goes away, but there's more to the series as it goes along. Quite a few contemporary societal issues are brought up, from government corruption to dealing with dementia to the dangers of widespread malware attacks. It's all done in a fairly light-hearted way, but it seemed clear to me that the writers wanted to give viewers something to think about beyond just the robot suits zipping around. You could pretty easily choose to ignore it, but those themes are there if you're inclined to consider them.
Active Raid is worth the time to watch if you're a fan of the police/military and/or mecha genres, as long as you don't mind that it doesn't take itself too seriously. It's unlikely to change your mind if you don't particularly like those genres, though.
