Not to mention The Hunger Games. She may not be the sole protagonist but Lawrence as Katniss is certainly the main draw for about 95% of the viewing audience for that franchise.
Also, Silver Linings Playbook - I mean, she did just win the best actress Oscar not even five months ago. So to say Lawrence can't carry a movie or be a main draw for one is really silly. She may not be at her peak yet but she has certainly arrived on the scene and established her star power.
