“Second Act” (**1/2 out of four) was an engaging but overly contrived romantic comedy about a middle-aged retail worker (Jennifer Lopez) who feels she is going nowhere in life and reinvents her life story and resume and lands a lucrative corporate job on Madison Avenue and soon captivates the professional industry with her street and business smarts. Lopez is likeable and charismatic as usual in a tailor-made role and there are some laughs in the script but story complications are predictable and a key plot twist midway through is pretty hard to swallow. Still, it’s agreeable and worth a look for Lopez fans.
