Don't see what's funny breh.
Loki was a villain that killed 80+ people in the first "Avengers".
They turned him into a joke side character/anti-hero. He was straight up comic relief in "Ragnarok".
Zemo was a villain that bombed the UN and killed the king of Wakanda in "Civil War".
Now he's hanging out with Falcon and Bucky, dancing and being used as fodder for memes.
The major difference is they took damn near a decade to do it with Loki. The last time we seen Zemo, he was literally a full blown terrorist that hated the Avengers. The jump from that to this series is jarring as fukk. Go re-watch "Civil War", then his first appearance in this series. It's damn near a completely different character.
