Level 16 was better than I expected. Maybe it's not a very original story, you might get a déjà-vu, but overall it was an entertaining movie. A slow build-up, but that only adds to the thrill and mystery, a dark story slowly unfolded. It was a bit of a predictable ending but even then it's still worth watching, especially if you're just looking for some easy mindless entertainment. It's not a high budget but you can't really tell, and it's not necessary either. The cast is well chosen, all characters were convincing in their parts. Level 16 is a decent movie in this genre.
