I'm glad they killed off Yondu. Rooker was just terrible as Yondu, and that bothered me every scene he was in. Yondu in the comics came off as more of a native american warrior type to me. Rooker just basically carried over his Walking Dead character, and that never felt right for Yondu.

Yeah there were only two that I would say were meaningful.
The Sly Stallone one with the original Guardians seems dumb, I know Disney is all about money, but if they're going to make movies out of all of these different comic book characters, and they already have the Guardians of the Galaxy up and running, why introduce another one? Especially if it doesn't live up to the team now, then you're just diluting the product.

The Groot teenager one would've been the one that I selected as the first after credit's scene, then the Adam Warlock one could be the final one. You only needed two.

The Stan Lee one was plain unnecessary. If you got the joke the first time,
then Great. No need to show an extended cut of that scene as post-credits though.

I thought one of most amazing things was the beginning scene, depicting a young Kurt Russell. I think they've pretty much perfected that process at this point - it just looked like a scene he shot in 1980. Far superior than what they did with Peter Cushing in Rogue One, and that was pretty damned good.

I was also happy to see that they got the 1980 Missouri license plates right. Miss the red plates.

Zombie Yondu?
