The hair thing was my only problem.
I'm finding all of the characters extremely likeable, especially now that the father has wised up.
The only way that scene could've been more forced is if he was holding a kitten the whole time. And the only way it could have been less believable is if he was dressed like Hitler.
Strucker Jr. is a stereotypical angsty little pube-rager. His friendly neighborhood cousin might as well have shouted "eSports! lolol!" while they were playing Kill Ratio. The uncle was a jerk. And mom just keeps coming off as an idiot. The daughter's best quality is that she's so blandly forgettable.
Agent Doorknob and Sentinel Services haven't made for very interesting antagonists. They're unlikable, but not in a delicious hateable villainous way. Shady Scientist Guy added the tiniest bit of intrigue without a shred of personality.
Meanwhile, The Miyagi, Not-Jean, Lightshow, and Scarface have been less like characters and more like decorations hanging from the hideous Strucker Tree. They might be likable if allowed to develop on their own, or if hung from different branches.
