While I am happy that "Up" had a chance to play a different character (and we all did really hate him), I'm disapointed in the story. Ming understands what he did was wrong, but he did not change his character that much. I can believe that he now really tries hard to be a better partner, but we have no idea if his control and power issues has been dealt with and I doubt it.
There were scenes where he was lying on the floor not eating, just drinking and not doing much, but this did not help to change his narcisistic flaws which are still present in the finale. I guess the screenwriter are contradicting the character because they wanted an redemption arc.

I also would have wished, they used "Winner" for the first part of the show and only "Poom" for the second half. This would of course complicated filming, because both actors would have to learn the same mannerisms for their characters which would have made the story more interesting and the immersion in the story more believeable. That the same person plays both characters irked me a bit.

I'm not happy with Mings character development and the same for Joe. Joe is always Joe not standing up for himself, not understanding when to say no. I can understand you love whom you love but there should be a moment when your brain says "enough is enough!". This show had so much potential, the first four episodes had me hooked and I thought about how they will solve the redemption. And because of the lack of a real redemption arc this show fails. For me the finale was especially lackluster because everyone is now "happy", all is good and even Mike got Mings secretary as future BF (They should have expanded that arc as well), because most of the later episodes is a repeat of the first ones without the violence and lack of self-reflection on Mings part but he forces Joe once again repeating the same mistake again.

So overall the show is still above average even when the story-writing falls of a cliff. It did at least try to do something different in the sea of average shows, it did try to give us a mature story in the sea of university settings. And Up as Ming was really great!
