I admit, I was in love with this series. I practically grew up with it and I was horribly dismayed to find that it had not been listed in ANY "Top [animes, TV shows]...." I read! The outstanding storylines, grounding character depth and overall awesomeness blew me away, but it seems that the brilliant anime did not get the proper recognition it deserved! I checked the trailers and advertising, which seemed fine, so I guess people just don't like the idea of epic card games with a dangerous Egyptian twist. :(. However, even I admit the constant ramblings of the characters as they explain (to the audience) the entire game gets a little tiresome. Very, very minor violence and blood (due to 4kids' strict dubbing).
Then there are the follow ons, GX, 5Ds, and the new Zexal. GX was very nearly as epic as the original, and I really did try to love 5Ds, but I couldn't get over the whole "card games on motorcycles" theme. Zexal? So far, Zexal has honestly just been one big, screwed up "WTF?!".
