“Bar Fight” (*1/2 out of four) was a witless romantic comedy about a couple (Melissa Fumaro and Luka Jones) who break up and decide to split everything that they had but start to bicker when they have to sort out who will have “custody” of their beloved bar that they have together. Generic comedy feels like it was spit out of a sitcom computer except “Cheers” told a similar story with far more laughs (and better drinks) about 40 years ago. By the end of this misfire, you may wish you had gone to an A.A. meeting instead.
