Zemo, easily, Daniel Bruhl brought humanity and purpose to this character, and at the end he achieved his goal which more than i can say about the rest.
I liked Ajax, he was weirdly likeable for me, a bit cliche but he made me laugh at times.
Apocalypse was dissapointing, so cliche and boring.
Lex was the greatest comedy relief ever, what a goofball, who said DC doesnt do comedy? Jesse was HILARIOUS, i lol'd so much at "DING DING DING" amazing comedy bit right there.
