Smaller plot lines were never resolved,

Rating: Null/10 (12 July 2011)

his film's biggest falters come in the form of the script. Despite the promise in the premise and the cast involved, the script was convoluted, and didn't have much structure until the second half. As a matter of fact, the film switches up the pace very unexpectedly when the next act approaches. Pretty much almost all the crude and vulgar humor failed to draw laughs, with one notable exception involving one of the odder "sex" scenes in recent memory. The movie was a great idea not exactly explored upon, and was full of smaller ideas that were not utilized. Many good smaller characters did not get enough time in the script; most notably the students, the gym teacher (Jason Segal) and the main character's roommate (Erik Stonestreet).
Despite the writing being a fickle mess, the cast was superb, from the small roles to the big ones. Cameron Diaz I can honestly say is one of the most underrated talents in Hollywood, because she rarely ever delivers a mediocre or weak performance. She has this aura, this energy that can save the worst of films (See: What Happens in Vegas) and it is no different here. Despite her smoking/drinking/vulgar/manipulative/cynical/cruel/superficial ways, we still secretly root for her to succeed in reaching her goal. Very few actresses can pull off this type of charm.
Lucy Punch, despite having a bit of questionable material, delivers as Diaz's rival. Jason Segal could have helped the movie a lot more if he was in it more often, as he delivered the laughs every time he was on- screen with his wit, sarcasm, and I-don't-care attitude. Television staples Phyllis Smith and Erik Stonestreet were hilarious in the far- too-few moments they were on-screen. The movie does indeed have its laughs, but the potential was so much greater considering all the talented actors involved.
Jake Kasdan as a director doesn't have much of a resume, but he does have the comedic chops and timing, and he proved this with the underrated Walk Hard. With Bad Teacher, he did not have as much good material to work with but could have still helped the movie if he had tightened the first third of the movie better. There was a lot more unnecessary fluff in the first half of the movie compared to the second half. Smaller plot lines were never resolved, certain jokes literally fell off without a punchline, and certain situations were brought up but never explored. Many concepts were also never explored: especially that of how shallow and shady we all become towards each other in the workforce.
