I would also say yes since all of the other anime series based on a TCG, as garfield15 mentioned, are either forgettable or the game doesn't make enough sense.
This was an enjoyable review to read and I agree with a lot of your points, Duke. I still remeraber the headache I got from watching the first two episodes after the Darkrai movie. I understand more of the basic stuff of the game, but I still wouldn't be able to play it myself. The rules become a bit clearer later on in the series, but that doesn't help those watching from the start.
I agree that if they had someone who was new to the game and needed to understand the rules, it would have made the show at least a bit better. At least that way, people would be able to follow the show's storyline without feeling so confused as to what the rules are. I think that series is fun to watch for the heck of it and the story became much better during the later stages of season one. Still, I think that they could have done a bit more to improve the storyline and the characters, mainly with doing a better job at explaining the rules of the game early on.
