It’s OK in the moment, and it evaporates as soon as the end credits roll. This is neither a uniquely marvelous film nor a teeth-gnashing pain. In that respect, The Rise of Gru does the job. In a dry summer that’s light on big blockbusters, The Rise of Gru - the fifth feature highlighting gibberish-spouting, indestructible, blobby henchmen the color of bananas (which happen to be their favorite fruit) just has to do its business, get out, and not dawdle in the mind for very long. Arriving in movie theaters just two weeks after Pixar’s high-profile, frustrating new science fiction epic Lightyear, the latest extension of Illumination Entertainment’s most popular franchise doesn’t have to be groundbreaking, memorable, or even particularly hilarious to make a splash. Minions: The Rise of Gru benefits from low expectations.
