Yes, it is funny when Skullboy and Poe fight in the kitchen and sound like a freaking married couple, but that’s it. I did not like how Skullboy was treating Poe. I usually am not the biggest fan of Poe, but in this episode he was trying to be kind, if for a selfish reason, by letting Skullboy stay. However, Skullboy learns that he is probably a descendant from a long line of layabouts. Meaning Poe is left to have a guest who does not just lay about, but will make messes without ever feeling any need to clean them up. He can be a layabout all he wants, but not if he’s a guest. Him saying „he’s taking me for granted“ when he and Poe are at counseling with Ruby, is rich.

Idk, it leaves a very bitter taste in my mouth and Skullboy never apologized

If Tai Lung and Master Shifu had been told early on, Tai Lung wouldn't have been driven as much because Master Shifu would have known no matter how much he would train him, his master had already told him it wouldn't make him the dragon warrior. So maybe things wouldn't have become as pressured and Tai Lung had grown up to simply accept his role as maybe a kung fu master, yet never the dragon warrior.

While unlikely, there is a slight chance Tigress wouldn't have been adopted by Shifu, so she wouldn't have been the one to gather the furious five. Yet, I doubt this, since Oogway would have just told Shifu to adopt her and she would then have been trained by Shifu and possibly Tai Lung.

Let's keep it simple, we end up where we were in the first movie. The furious five are gathered, they become masters but there is no threat as to why the dragon warrior would be chosen. Oogway could just say "we're doing it today because I feel like it" but that still doesn't change the issue. So Po ends up becoming the dragon warrior, because there was no other way this would have gone and then what? There is no pressure, no reason for him to train, no reason for him to be motivated and keep going. There is no one to fight and yet he has to be ready for Shen at some point.

He has to become the dragon warrior and understand what the scroll intended, then be ready for Shen but there was no opportunity for him to rise to. So he fights Shen, but isn't ready for the big thing. If he failed because of that, he wouldn't be able to stop Shen. He would sooner or later find the rest of the Pandas, especially since he was never stopped. All Pandas would have been eradicated and once Kay would come back, everything is over, because there is no one around to stop him.

Oogway himself said (paraphrasing) that he was never destined to stop Kay and send someone else on that path. Yet if Po had already failed at Shen, he wouldn't have stopped Kay.

(I now have to sadly admit, I did not watch the fourth movie, so if there is something contradicting my theory, tell me. I just couldn't bare Aquafina and worse, the whole trope of: old legend passes on the torch)
