Totallly disagree about Enfys Nest. First she was not a "baddie" (that was Dryden Vos) so the fact that she did not come across as an effective one you could argue is the point. Second the fact that she was a young idealistic freedom fighter perfectly embodied the youth and idealism of what would eventually become the rebellion.

Here are some worse additions...

Knights of Ren
Rose Tico
Captain Phasma
Zori Bliss

"Rogue One" has to be one of the most overrated films of the last decade and this nonsense is why.

iT iS sTaR wArS fOr aDuLtS ... which apparently means you can explain away serious storytelling deficiencies.

And the lack of character development was a problem in "Rogue One". I didn't need a long back story for everyone but better defined their characters would have been nice. 

The dialogue among the protagonists sounded like it could have all come from the same character. 

How are they fleshed out beyond them telling us or us seeing what they did in their pasts? 

I've loved Felicity Jones and Diego Luna in other films, but here they made no impact.

Mads Mikkelsen provided that element of humanity best.

Jones didn't connect at all.

Tragedy works BECAUSE audiences cares what happens to the characters.

And it's flat-out offensive to claim that Rey was one of the worst characters while Jyn was one of the best.

"The Force Awakens" succeeded because it introduces these characters, gives you a feel of who they are as people, and then creates a story where we are invested about what happens to them.

It invoked real emotion in the story as we watched them undergo their conflicts and triumphs. The audience feels these emotional beats in the story.

And Ridley had big-screen charisma and charm, unlike Jones who always looked uncomfortable and brought zero weight or credibility to her supposedly tough character.

For giggles, I put this into the main page's search bar.

Which brought up this same list, from last October...
