I thought they were both lame and wasted potential honestly.
Avengers 2 had its great moments yeah, but as a whole it felt kind of bloated to me with just how much they packed into it. I wish Vision was more developed, especially in hindsight with how little screentime he had before getting axed in Infinity War. And, look I'm not gonna pretend I'm some uber comics nerd because I'm not, but you know an Ultron I totally love? The one from Avengers: EMH. THAT Ultron was fucking great, and something at least vaguely on the same wavelength was what I expected from Ultron in the film, but he kinda acts like some regular joe. Some people like him but to me, it feels like a betrayal of his potential.
A lot of things about Civil War made no sense to me, but without getting into nitpicking Tony's motivations (and complaining about the dumb final Iron Man vs Cap fight), I mainly just wanted more hero fights (the airport was a boring location) and a better Zemo. I mean on his own in the film, he was perfectly fine, but like he's just some guy, not Zemo.
At least Black Panther was great in it.
