For the longest time I've failed to remember the name of a movie, which was definitely released post-2000. I think the main character had a buzz cut, and it opened either on a military base or in a prison, from where the main character and one (possibly a few more) are teleported somewhere for duty/serving their sentence through work. If I don't remember this incorrectly, the teleportation is preceded by some alarm going off, and is carried out by some sort of small device they put on their persons, maybe a necklace-type thing.
The work in question is to investigate a research station that has gone dark. From there on the common horror tropes of people getting killed one by one ensues, though the details elude my memory. However, I do remember that towards the end it is revealed that some kind of sentient slime was behind it all; it kind of possessed people and made them do its bidding. I think the main character was the only survivor by the end, and reached a truce by simply convincing the slime that he was no threat and asked it to stop.
