Sector 7 (2011)
What can I say about this one lol It took what felt like forever to get going and had a ton of really dodgy CGI and awkward green screen work. They could've done with showing the monster a lot less. The green screen stuff just felt so lazy and unnecessary, especially when all they did was walk down a hallway in an oil rig with nothing really happening. Surely it wouldn't blow up their budget to walk down a real life hallway instead of an animated one. The film is also filled with cliches, but I can live with that. It's a popcorn movie after all.
I still had some fun with it, and the main girl was just super cute - as expected from a Korean film. Fighting the monster was made into a real struggle, which I liked. It had it's funny moments as well, and I liked how the main chick turned into Ethan Hunt suddenly with some bonkers motorcycling skills (yes, they have motorcycles on oil rigs in South Korea).
It won't get a high rating from me, but I don't regret watching it either. Even when it's quite bad, Korean cinema manages to keep me somewhat entertained. Some of the acting performances were also quite enjoyable. 5/10
