It would hurt me equally if the Kaiba brothers separated at the end and didn't give a damn. It particularly hurts me because I love Yuugi and Yami as much as Mokuba and Seto, so the ending completely breaks my heart. Seriously, I could write a LOT about how pissed off I am about that. I can understand that Yami belongs in the afterlife and that he had to leave, but I still expected a much more powerful ending. I have no words to really describe how much that disturbs me because two people who are as close as Yuugi and Yami should have shown FAR more emotion at the ending. I felt like there was very little love and Yuugi and the others all moved on really quickly, which severely disturbs me. Actually, the crappy animation is one hint that the ending was rushed. I also despise the Yu-Gi-Oh! ending because Yami left really quickly and the whole ending was so horribly rushed. :/ As much as I normally love Seto, I'm very disappointed in how he behaved in season 5. Ugh, I hate how rude Seto was towards Mokuba in that season! I don't understand why he was that rude since he was sweet to Mokuba in Duelist Kingdom and Noa's virtual world, but Seto somehow became a horrid jerk in the Millennium World/Dawn of the Duel. Yeah, there are many reasons why I hate season 5, including the reasons that you mentioned.

I wish Tara had voiced Mokuba for season 5. Then later she returned to 4Kids to voice Leo from Yu-Gi-Oh! 5D's, but it wasn't the same for me because I don't like 5D's as much as DM (the series that Mokuba is in). She replaced the first female host and stayed with the block until 2007. :C I heard that Tara stopped voicing Mokuba because she temporarily left 4Kids to be the co-host for Fridays on Cartoon Network. Caroline simply didn't know how to imitate the voice that Tara had given him. It would be like a lower pitched version of the voice he has as a child, but it would NOT sound like that horrid voice that Caroline Lawson gave him. Some fans said he was going through puberty, but I disagree because I can imagine how Mokuba's voice would sound like as a teenager. xD It was funny how Chase sounded exactly like Mokuba lol~ Anyway, Mokuba was voiced by Caroline Lawson in season 5 and he sounded awful. Tara gave the same voice to Chase, the main character of Fighting Foodons. I cherish the voice that Tara Sands gave him. I know! D: I immediately realized that Mokuba's voice was different when I first watched episode 185 because he's one of my favorite characters from Yu-Gi-Oh! and I was extremely disappointed that he had such a different voice in season 5.

Yu gi oh voice cast
