It is your cliche WW2 movie. D-day happens, paratroopers knee deep in flak fire. It had it's fair share of it and being a J.J Abrams movie, it had to be a hybrid. This time it was zombies. If you are a gamer, then you would enjoy this Wolfenstein, Nazi zombies style movie. But if you are a nut for WW2 movies, the movie sounds like a joke .With it's inaccuracies scattered fairly along the movie. You would need to look hard to even notice the mistakes. I really enjoyed the special effects, sound works and ,although easily anticipated, the jumpscares. I wanted it to be more horror as you only get three scares and that's that.
In the end, Overlord ticks the boxes for an abstract, WW2 movie with a hint of crazy. I would recommend it if you enjoy these kinds of movies. I am not a critic but this movie deserves a 7.5/10.
