[Matrixbeast]

I dropped the anime around the middle to end of GX. Jaden was annoying, never lost, was a complete monster ("Lemme sacrifice all my friends and allies I made over the past 2 seasons so I can save one guy I met a month ago!"), and was constantly pulling new BS E-Hero fusions out his ass whenever it seemed like he was on the verge of experiencing a loss.
I couldn't stand Jaden, so the anime was too hard to sit through. 5Ds' premise was fine, but it's execution was far too...Dumb. It felt like a 90's show made a decade late.
