TheMarvel Cinematic Universeis filled to the brim with absolutely lovable characters on both sides of good and evil.

However, with each group of beloved characters comes a few disliked and even hated ones.

This franchise isn’t perfect and neither is its writing.

There are a few, however, that are disliked far more than the others.

Ghost had potential from the start, given her unique powers and the origins of them.

Thankfully, her potential can hopefully be expanded upon inThunderbolts*.

Most people had zero problems with the identity change from Anthony Masters to Antonia Dreykov (Olga Kurylenko).

It was a major problem when they changed the character’s powers and looks.

This was not the case with Antonia, as she was far weaker.

As Scott Lang balances being both a superhero and a father, Hope van Dyne and Dr. Hank Pym present an urgent new mission that finds the Ant-Man fighting alongside The Wasp to uncover secrets from their past.

This is a shame, as she could have been a much better villain given the right attention.

Natasha Romanoff confronts the darker parts of her ledger when a dangerous conspiracy with ties to her past arises.

Most of his hate comes from the fact that he’s simply poorly written and feels redundant.

Unfortunately, the dislike for the character grows now knowing what could have been.

Most of his hate comes from the fact that he’s simply poorly written and feels redundant.

There are a lot of things that went wrong with Malekith, most notably the writing behind him.

There’s nothing wrong with Christopher Eccleston besides the fact that he’s unbearably unrecognizable in the role.

It’s a great shame that the phenomenal Eccleston was wasted on such a poorly written role.

That is also another reason many find to hate this character.

It was shaping up to be the best film of the three.

With the world now aware of his identity as Iron Man, Tony Stark must contend with both his declining health and a vengeful mad man with ties to his father’s legacy.

So, in this instance, the writers did a great job at bringing Walker to the small screen.

This was the most upset Marvel fans had been in quite some time.

There’s not much to say about Ralph Bohner that hasn’t already been said a thousand times over.

There are few-to-no complaints about actress Erin Kellyman.

People truly just did not like the way the young Flag Smasher was implemented into the series.

Some claim that her character arc is contradictory or just all around bad.
