It sounds like Tubi has their hands on an action-comedy gem, as Black Dynamite and Blood and Bone star Michael Jai White returns to the genre in Dont Mess With Grandma. The movie has now debuted at Fantastic Fest and the first reviews hail Dont Mess With Grandma (which was formerly titled Sunset Superman) as the perfect twist on the home invasion movie, with White proving once again that he is the unsung hero of action movies.
