First of all let me say the Dirty Pair is the series that got me into anime 20 years ago. Dirty Pair consists of 3 series and 3 movies (although Affair On Norlandia and Flight 005 Conspiracy I consider to be ovas) while Project Eden is a true movie. Kei and Yuri are called the Dirty Pair because of their habit of leaving destruction in their wake during their assignments. Dirty Pair-Flash is considered the red headed stepchild of the franchise. Now on to my opinions on the series. As the 26 episode original series is very episodic you don't have to be intimately familiar to jump in at any point and start watching. Kei and Yuri are best friends and argue but have each other's backs in the 1st series and the ovas and movie. In the Flash series they have been re imagined and hate each other and have very different personalities. Kei is the redhead and has a fiery temper, is somewhat butch and was probably a tomboy when she was a child while Yuri is much more feminine, has blue hair. Kei's weapon of choice is her trusty blaster, Yuri can use a gun proficiently but prefers energy whips or throwing cards. I think the Dirty Pair is quite entertaining to watch even though it reflects the era of the 80's when it was made. The episodes are kind of formulaic and predictable but fun in a mindless sort of way. There is a lot of banter between the two of them and a lot of it is the kind of stuff good friends talk about. Looking back at the series from a lens of 20 years the Dirty Pair is still one of my all-time favorite series. I can recommend it without reservation to anyone looking for a sci fi/comedy show that doesn't require a lot of thinking to watch.
