I'm not sure if the person below has only seen the first 10 episodes, or the entire series, but either way I completely disagree with him.
As an anime fan, I have to say R.O.D. is perhaps one of the most gorgeously drawn and well written animes of all time. It might start out slowly for some, but once it picks up it truly becomes enthralling. R.O.D. The TV offers more in depth characters and subplots (which were lacking in the Read or Die OVA). The plot focuses around 3 sisters who are all paper users and a Japanese author. The characters from the OVA show up as the series progresses.
I highly recommend the anime for all fans. You do not need to see the OVA, but the second half of the series will make more sense with it.
