Since 1984's The Terminator Sarah Connor has been a big part of the Terminator franchise, She's had her parts in the Comics and Novels, she's so far had 6 figures, and she's been played as a strong independent woman in Terminator 2: Judgment Day, The Sarah Connor Chronicles and Genisys.
But her actresses have been argued for who was the best: Linda Hamilton, Lena Headey and Emilia Clarke.
Let's start with Linda Hamilton's portrayal of Sarah in The Terminator and its hit sequel, Terminator 2: Judgment Day. When we first meet Linda's Sarah, she is a timid, mousy, friendly college student and waitress who had no idea of her destiny, then the Cyberdyne Systems T-800 Model 101 Terminator and Kyle Reese show up and changed Sarah's life forever, she relied on Reese to protect her BUT she has learned over the course of the film and even destroys the Terminator in a hydraulic press (With a broken leg by the way). When we meet Linda again as Sarah in Terminator 2: Judgment Day, She is a tough as nails, ripped, weapon using badass warrior who struggles with protecting her son and with losing her humanity over the course of the film, She tries to warn humanity about Skynet and Judgment Day and so is locked up, She breaks out and escapes with the help of her son, John and the Cyberdyne Systems T-800 Model 101 Version 2.4 Terminator, whom she is terrified of when she first laid eyes on him, and was distrusting of at first, and run from the T-1000 Terminator, She learns about the man directly responsible for creating Skynet and the Terminators, Miles Bennett Dyson and sets out to kill him becoming a Human Terminator BUT stops because she realizes what she is doing and helps John, The Terminator and Miles destroy Cyberdyne and Helps destroy the T-1000 and destroys the T-800. Even though Linda portrayed Sarah Connor in two Terminator films, She is labelled as one of the most badass science fiction characters, next to Ellen Ripley and is the most badass movie mother as well.
I give Linda Hamilton's Sarah Connor a rating of 10/10.
Now let's look at Lena Headey as Sarah Connor in the 2008-2009 television series Terminator: The Sarah Connor Chronicles. She continues protecting her son from Skynet's Terminators with the help of a female Terminator: Series 900 Class TOK715 Codenamed "Cameron", She is still tough as nails, Although Lena's portrayal has a lot to be desired for me, everyone has their own opinions on Lena as Sarah, Mines just mixed.
I give Lena Headey's Sarah Connor a rating of 9/10
Let's wrap this up with Emilia Clarke's Portrayal of Sarah in 2015's Terminator Genisys, Now I thought it was great seeing Sarah Connor in the films again, I liked how she had the T2 Sarah Connor Personality and she actually trusted the T-800 protecting her the whole time, not like her Hamilton counterpart, Which took awhile to trust The Terminator, I thought she didn't do that bad of a job. PS I know some didn't like Genisys and some did, But I'm not talking about the film, I'm just talking about Sarah Connor.
I give Emilia Clarke's Sarah Connor a rating of 9/10.
