GX Season 1- In this season, they didn't really get to the main plot untill later on. With that said, they did give "hint's" to what was coming. They were showing us "Judai's character" in his many duel's. Each duel was set under a different circumstance, forcing Judai to act differently. This obviously showed us part's of his personality & helped us to understand his character. These dule's also helped set the over all tone of the new Yu-Gi-Oh!, showing us that this was a different show & wasnt anything like Yu-Gi-Oh! DM. I enjoyed this season.
GX Season 2- This season introduced a few new character's. It also showed us that Judai's deck wasn't exclusive to him. Judai being the new main character, had to stand out & have his own exclusive deck/card's. With one defeat, Judai was forced to tweak his style a bit & so the "Neo's" deck was born. Later on in this season, Judai duel's a few "pro's". This helped us see the improvment/growth in him. This season had many great concept's & really pushed on the topic of "Good vs Evil" in human's. The Boss battle could have been better, but I enjoyed this season aswell.
GX Season 3- Season three was awesome. Again, like season two we got new character's. They focused alot on Judai's growth as a person, opposed to his growth as a duelist. They took the show in a different direction with the "duel monster card's" dueling. That was a cool twist for me. Like in Yu-Gi-Oh! DM, the main character of this Yu-Gi-Oh! turned evil for a little while. This also helped us understand his character more. Season three took a darker turn, but it was great. I enjoyed this season too.
GX Season 4- The best season yet. Judai come's back all sexy/hot-er ><. He's given new power's & a new demeanor. Wich, was very hot..They showed us some old character's & there growth's. Plus, the epic duel with Judai & Yugi. A really great season of GX. I loved it ><
