If you’re a child of the 80s or 90s, you might have made a mixtape or two.  I did!  Every week!  The very joy of compiling songs to give your listeners the feels.  That is displayed in the new coming-of-age drama “Mixtape.”  Gemma Brooke Allen is Beverly, a young orphan girl living with her grandmother Gail (Julie Bowen).  Her parents died in a car accident and the only connection Beverly has with them is a mixtape that belonged to her mother.
