Abandon all brains, ye who enter here - this must be your rule if you watch Osiris. The logic failures are too many to count: the aliens are heavily infected with the well-known Stormtrooper syndrome (like the terrorists in the beginning), and our heroes seem to have the unlimited ammo cheat. On top of that, they most of the time forget they got grenades to use or take the powerful alien guns from the dead and just use them...
Anyway, if you're able to switch off your brain, you'll get some B-trash action that's entertaining to a certain degree. But in the last third, it runs out of steam and gets boring - too much bumbum and nothing else. In this sense, it reminds me of the last Wick movies, including Ballerina.
Still, the production isn't too bad, and the entertainment factor - if you like this kind of action movie - is okay. Like many movies these days, Osiris mostly lacks a well-written script, and the story and ideas feel like they were just "glued together" by some AI from other action and sci-fi films. To mind come movies like Predator, Pandorum, Doom etc.
