It's very hard to root for Daniel in these three movies, especially the original and the 3rd movie. Part 2, I thought he was okay, he was helping Miyagi (though he could have paid for his own ticket. Just saying!), he was cool and friendly and I thought Chozen was being a dick for no reason. I even liked Daniel and Kumiko together and I was disappointed he and Kumiko weren't married on Cobra Kai. Daniel left Kumiko on good terms.
I still think Daniel wasn't bullied on the first movie. The Cobra Kai boys only attacked Daniel when Daniel did something to them, it wasn't as if he was being beat up for no reason. When Daniel kept his distance from Ali or wasn't trying to be a tough guy, Johnny left him alone. Johnny did go too far with the beating at the alley, even if Daniel provoked them.
In Part III, is where Daniel lost me. He was always bitchy and whiny but in Part III, I couldn't stand him. Always complaining, he treated Miyagi like crap because Miyagi wouldn't train him into knowing more deadlier movies, being fooled by Terry Silver and then getting his ass beat up by Mike Barnes. At that stage, Daniel shouldn't be a scaredy cat but he was still acting like one. Not to mention, not going to college and being a parasite in Miyagi's home where he was living.
