Obviousley Ali Larter has been a star for a while now. She has mastered the horror genre and did some work regarding comdedy. She showed off her screams and worried faces in the first two ' Final Destination ' movies and then took it to the next level in the third ' Resident Evil ' so there is not doubt about it that this woman can act. Now we can see Ali Larter on Heroes. She has been on Heroes from episode one and on Heroes we have seen her develop her acting skills. For the first two seasons Ali Larter did great as Nikki Sanders. A mother of a child who can talk to machines while she has a split personality. It's superb how she could transform herself from the innocent, caring and nurtouring Nikki Sanders into the evil,sexy and Mischiveous Jessica in a matter of seconds. I like everything about Ali's performances except for one thing. Sometimes she dosen't react in scenes as well as she should because I think that she thinks her face is good enough for all expressions if she just stands there. Like in Volume 3 of Heroes. All she does is talk and smile when she's being evil. When Tracy was going to kill herself, she just stood there with no expressions and threw herslef off the bridge. I'm not sure whether Ali is slipping as an actress or if it's this character Tracy which isn't letting Ali get to her full potential. Either way Ali needs to expand her horizons with more movie roles and different shows. She's always my favorite on Heroes but I think it would be better for her if she left the show. In conclusion Ali is magnificent and outstanding as an actress in my oponion and I deffinately want to see more of her :D

Ali Larter was ok as Nikki, however her role on Heroes was overused for a long time. I was so glad to have Nikki die in the show, only to figure out the writers brought in Tracy just to keep Ali Larter in the show. The actress herself is god awful at acting and quite annoying. I always hated her in the show and thought she was a big waste of time, money, and space.

Tracy was one of the most bipolar characters and I really hated the way she was trying to control everyone. She was more bipolar than Elle. At first she was a prostitute trying to get Nathan into the public's eye, then she becomes the innocent girl framed by the media, and then she's the emo girl who tries to kill herself, falls in love, and then goes right back to the prostitute who's trying to control everyone and everything. She was sooooooo annoying. The best part of this past season was when Hiro punched her in her face. She deserved that.

Ali Larter stinks as an actress and she always does the same annoying face expressions. Her smile is so annoying the way all her teeth show. It really bothers me the way everyone thinks she's a good actress. She has no idea what she's doing in front of the camera.

The entire Tracy thing was a complete waste of time on the show and could've easily saved time for more character development on the MAIN characters, instead of focusing on a nobody who didn't even drive the story forward. Everything she did had no point in the story and everyone would've gotten to the same spot had she not been there. I really hated the way the last episode of Villains ended where she was seen picking up Mohinder and flashing that annoying smile. If the writers really cared about the show they won't waste our time with that sorry excuse of an actress and just kill her off the show for good.

I love Ali Later . She plays Nikki / Jessica in Heroes and she is perfect for that role . I would not love those characters if they're not played by her ! She really brings the spirit in her characters and we can see she is so talented ! I just love her ! She's very pretty and I love her eyes . . . She is so cute when she's sad . . . And she is so sexy when she plays Jessica . . . :D :D :D All in all, Ali is a great actresses and she's so talented and I love her very much! :)

Ali Larter is the best actor on Heroes. Her role on the show, Niki/Jessica is just awesome! It takes to be great to do what she does on the TV show! She should have her own show or a spin-off when Heroes is over, because she really deserves it! I just love her!
She manages to do everything just great! To play a role where she must be two at the same time it is not easy and she is doing amazing!

She should be on the air a long time ago, that's for sure!

Ali Larter, you are the best ever! ;)
