Since DC/WB has been making movies since how long and have the rights to all the characters, WB/DC prints the comics...Steel? Swamp thing? Superman 3/4? Supergirl? SS? Batman Lex and doomsday? ( you can i guess let Doomsday Slide since he is a mindless monster, but didnt like the way he looked and some of his powers) GL? Catwoman? Batman Forever? Batman & Robin? Flash is getting old fast with this monster of the week and Arrow has been meh since season 2

Ironman 1 villain just fine, Ironman 2 Whiplash wtf? but hammer was just fine, Thor loki/frost giants that movie was 101 for any new comer to Thor so just fine? Ironman 3 i kinda liked the twist, but i can see how people didnt like the main villain that clam to be the real one, Thor 2 bad, Cap red skull was okay/passable, Cap 2 great, GotG Ronan not really & that blue chick forget her name lost some comic cred but she was passable, Avengers Loki great/ aliens good, Cap 3 Zemo i rather see the comic version but his overall plan was a bit extreme overall enjoyed him, AoU Ultron since this was tony/bruce making i understand the wise cracking, i didn like the fact how i never really feel the Avengers was in trouble,Ant-man passable ( he kinda remind me of ultron from the comics, but without being ultron) and Hulk it was a mindless monster vs a semi not mindless monster lol so meh.

Kevin said the problem with most of the villains is that they need to keep them grounded and tone down.
