I watched "Don't Mess With Grandma" because I have enjoyed some of Michael Jai White's other films, in particular, the cult favorite "Black Dynamite". And, while White once again beats the snot out of some jerks, this time he's older, less confident and not quite the invincible superhero.
Jasper (White) goes to his grandma's house and it soon is clear her hearing isn't very good and she's a tad oblivious. During this time at her house, some burglars arrive and try to break in...and Jasper pummels them. So, they bring more friends, and Jasper pummels them...and his grandma's pitbull kills one of them. So, they bring in more friends. Why? And, what's next? See the film.
This is not a great film but made me laugh quite a few times. I also appreciate how White is now well into his 50s...and while tough, he's NOT the man of steel. A clever comedy...though also one with an obviously low budget and modest pretensions. Worth seeing it you like White's work...otherwise, you might be able to skip this one.
