This was bad *potential spoilers*
The trailers made this look really thrilling and action packed. Instead what I saw was an uninspired, boring and dull war film with a tiny bit of zombie horror in there. It's not scary, it's not suspenseful and the attempts at comic relief fall flat. A lot of the film is spent inside a house with paper thin characters just making absolutely dumb decisions just to get the movie rolling forward. At only 110 minutes this felt long and you honestly wonder when the flesh-eating monsters are actually going to show up and when they finally do it's too little too late.
If you're promising a genre shift in your film to horror at least make that element good. Instead you get 80 minutes of dull wartime drama with a couple of weak jump scares and a final 30 minutes of over the top, predictable silliness with awful one liners and a lame villain who monologues too much.
The opening scene with the paratroopers jumping from the plane was quite intense and had good CGI and sound design, as did most of the film but that was about all it had going for it. This had the potential to be so much better, it could have been the next Bone Tomahawk, a film that worked as both a western and a horror whereas Overlord fails as a genre blend of war and horror and instead delivers a dull and unmemorable film with one note characters and very few thrills or scares.
4/10
