“Don’t Think Twice” (*1/2 out of four) was a clunky romantic comedy about a NYC couple (Keegan Michael Key and Gillian Jacobs) who work as an improv group in comedy clubs but have their own individual aspirations of appearing on a weekly and popular television show. Irritatingly unfunny comedy rings false at every turn and makes one appreciate the rich writing and originality of Woody Allen which this was obviously inspired by. Ben Stiller has a needless and unnecessary cameo. Don’t think once about wasting your time on this trifle.
