Kaley Cuoco
> Kaley Cuoco, who has played the character Penny on "The Big Bang Theory" for
> the last seven seasons, is an actress who could use a few more acting classes.
> Those who watch the show might agree that her character brings sex appeal to
> the show, but not much else.
> One might wonder why the creators of the show don't just replace her with
> another pretty face who can indeed act.
>
> Jared Gilmore
> Jared Gilmore plays Henry on the popular fairy-tales turned into real life
> characters show "Once Upon a Time," but the early seasons focused way too much
> on Henry's annoying perspective and exposition-heavy dialogue. Thankfully, as
> the show progresses, he becomes much less of the story's focus. >
> Laura Prepon
> Sure, Laura Prepon is cute, tall, and redheaded. She was Eric Forman's love
> interest on "That '70s Show" for several seasons, but nearly every scene that
> she was in felt forced and had all of the humor sucked out of it. It isn't
> clear why she was unable to play Donna well, because her role on "Orange Is
> the New Black" showed much better acting.
> Maybe she took some acting lessons between the two series.
>
> Adrian Grenier
> Adrian Grenier, whom you might remember as the lead on "Entourage," had the
> weakest acting skills of anyone else on the show. That might include the
> extras as well as the supporting cast. Grenier has had exactly four acting
> gigs in the years since "Entourage" ended, and one of them was an "Entourage"
> movie.
>
> Cathy Cahlin Ryan
> "The Shield" was one of the best television series of the past couple of
> decades, and Michael Chiklis was one of the major reasons why. Nevertheless,
> Cathy Cahlin Ryan, who played Corrine Mackey on the series, was the opposite
> end of the spectrum, making a good series worse for her part in it.However,
> she wasn't the only bad actor on the show; Chiklis' real-life wife, Autumn,
> also had some problems with believability.
>
> Nolan Gould
> Okay, so Nolan Gould, who plays Luke Dunphy on "Modern Family," is just a kid.
> You can't blame him for his bad acting, but you can blame the casting director
> for "Modern Family. " Gould's lines are stiff and wooden, and if you replaced
> him with that robot that beat everyone on "Jeopardy," you might not be able to
> tell the difference.
>
> Jonathan Ahdout
> When it came time for season 4 of "24" and the character of Behrooz Araz, the
> casting director failed his or her job miserably. Every line that Jonathan
> Ahdout delivered was toneless. It makes you wonder if he had something on the
> producers of "24" to keep him from losing his job.
> Thankfully, his character was here and gone in season 4.
>
> Chandler Riggs
> "The Walking Dead" is one of the best shows on television; however, Chandler
> Riggs, who plays Carl Grimes, is not living up to his potential. Carl has some
> great lines on the show and some great moments with Rick, but Riggs just isn't
> able to bring the emotion that would make his character endearing and likable. >
> Gillian Anderson
> Gillian Anderson would probably be best at the end of this list, were it in
> any particular order. Agent Dana Scully wasn't that unbelievable on "The X-
> Files," but when it came to showing real emotion, when tension was at its
> highest, Gillian simply didn't bring it. Part of this might have been the
> squabbles that insiders say existed between her and Duchovny and the lack of
> chemistry in later seasons.
>
> Jerry Seinfeld
> Jerry Seinfeld is funny, and his self-titled television show was hilarious,
> but among the excellent level of acting on that show, Jerry was the only one
> who you could tell was acting.
I somehow always thought Martin Sheen looked like he was about to start laughing in pretty much every scene.
