Seriously, she's a terrible actress, how can anyone like her?

Excellent points Austin. Case in point: Two of Hollywood's biggest box office draws over the past 15 years, Tom Cruise and Angelina Jolie, are ranked #1 and #2 on Ranker's "The Most Annoying A-List Actors" list: http://www.ranker.com/list/most-annoying-a-list-actors/ranker-film

So that would be somewhat of an oxymoron to have two actors who are widely considered to be annoying are paid several million for each role they are cast in, when taken in the context of the OP which states that because an actor is considered by many to be annoying, that such an actor should not continue to be cast in films.

I myself don't consider either actor to be annoying at all. For example there was nothing annoying about watching Tom's performances, in chronological order of his appearances in the movies: "The Outsiders", "Risky Business", "All the Right Moves", "Legend", "Top Gun", "The Color of Money", "Rain Man", "Born on the Fourth of July", "Days of Thunder", "Far and Away", "A Few Good Men", "The Firm", "Interview with the Vampire", "Mission: Impossible", "Jerry Maguire", "Eyes Wide Shut", "Magnolia", "Mission: Impossible II", "The Others", "Vanilla Sky", "Minority Report", "Narc", "The Last Samurai", "Collateral", "War of the Worlds", Mission: Impossible III", "Tropic Thunder", "Valkyrie", "Mission: Impossible - Ghost Protocol", "Jack Reacher", Edge of Tomorrow", "Mission: Impossible - Rogue Nation", "Jack Reacher: Never Go Back".

And likewise I find nothing annoying about watching Angelina's performances, in the chronological order of her appearances in the movies: "Playing by Heart", "Pushing Tin", "The Bone Collector", "Girl, Interrupted", "Gone in 60 Seconds", "Lara Croft: Tomb Raider", "Original Sin", "Lara Croft Tomb Raider: The Cradle of Life", "Sky Captain and the World of Tomorrow", "Mr. & Mrs. Smith", "The Good Shepherd", "A Mighty Heart", "Wanted", "Changeling", "Salt" and "Maleficent".

Good points as well Sentient, as I believe many casual fans and observers would probably agree with most of what you stated. I couldn't agree more that indie roles suit her the best since my personal fave performances of her have all been in indies (i.e., Clouds of Sils Maria, Adventureland, Still Alice, The Runaways, The Cake Eaters, Into the Wild, Speak). While I'm not really a fan of The Twilight Saga films, just the fact that she helped anchor the highest grossing female oriented film franchise of all time speaks volumes. Unfortunately for her, like you mentioned, it was a double edged sword in that the paparazzi and gossip rags never let her out of their sight, which must have been difficult for a young actress who doesn't prefer the limelight. You do have a point when you say she's average looking by Hollywood standards, from the perspective that in the roles most know her by, she portrays the average girl next door, oftentimes a troubled teen. However, when she's all dolled up, I consider her to be one of the prettiest young actresses working in Hollywood today. And there must be a good reason why she is the face of Chanel's makeup line and models extensively for Chanel. I've been wanting Kristen to star in a superhero franchise primarily for exposure, in order to show mainstream audiences that she does possess a measure of acting talent--as most only know her by Twilight--and obviously most haven't seen her small budget indies, well at least not in theaters. So thankfully she has been cast in the big budget film "Underwater", which is not exactly a superhero flick, but will afford her the opportunity to star in a kickass role in a studio tentpole, which might suit her even better than a superhero franchise probably would. While starring in a superhero role is relatively uncharted territory for Kristen, it does not come without precedent as the fifth installment of Twilight, "Breaking Dawn - Part 2", she did play a vampire with superhuman strength. And of course there's her role as Snow in "Snow White and the Huntsman", where she portrayed another kickass heroine, a film which actually did pretty well at the box office, grossing nearly $400 million worldwide, which was much better than "The Huntsman: Winter's War" did despite retaining all of the stars from SWATH, except for Kristen, while adding Emily Blunt and Jessica Chastain. Speaking of working with directors during the '70s, I would have loved to have seen Kristen perform in a role similar to Gena Rowland's role in indie film pioneer John Cassavetes' 1974 film "A Woman Under the Influence." In an interview, Kristen even mentioned how she considered Rowland's performance as one of the most influential roles on her as a young actress growing up in Hollywood.

If there is one role I would recommend that showcases her acting talent, it would have to be "Clouds of Sils Maria". In my opinion, she put on an acting clinic with her performance. And many would probably agree as she became the first American actress to have ever won a Cesar award for her role as Valentine. She also received lots of critical acclaim for this role, most notably, first place critics groups awards from both the New York Film Critics Circle and National Society of Film Critics as well as a second place award from the Los Angeles Film Critics Association. These three critics groups are widely considered to be the three most prestigious film critics groups in the world.
