Watched both ROD months ago, though in Japanese. I too found it a very good and balanced action series without any below average episodes. I think I preferred the more funny tone of the OVA. Some characters in the TV adaptation were a little too serious.
I recommend it as well as one original action series. Now with all the flux of various new shows it is very difficult to spot such series and even more difficult to find time and to not be prejudiced.
Even during its release date there were so many good series that I skipped it.l
Cool! You have to understand it's been years since I've discussed this series with anyone, so I'm thrilled that anyone knows what the heck I'm talking about.
And I would recommend you watch it again dubbed if you're so inclined, specifically the TV series, the OVA dub is fine but nothing super noteworthy (save for the fact that the blond Smoking Gunmen guy from The X-Files voices one of the characters)
But what makes the TV series dub so good is the fact that the actors and actresses in it aren't in a whole lot of other anime (in some cases not a whole lot of other things period), so their voices sound more unique to the characters and not "Crispin Freeman/Johnny Yong Bosch character number 9000" like many English dubs.
On top of that the British characters are voiced by actual British actors, which is really cool (same company that did the English dub for the Hellsing franchise in fact, which was also similarly an anime with British actors, I wish we saw more of that), this works best for Yomiko Readman herself, who was a different actress in the OVA, who was fine, but she really sounds great in the TV series, like I said it's the same actress who does Bayonetta (and for more video game connections an actor named JB Blanc is in R.O.D The TV, who was also in Saints Row 4 and Horizon Zero Dawn and a few of the different actors pop up in Marvel vs Capcom 3)
And finally, the script is not a super direct literal translation, though it doesn't stray too far, but it has the effect of making the dialog feel more natural, which is what I prefer.
It's just overall probably the most unique dub I've ever heard.
