Drama, well um yes some, Horror, yes there are some horror in this movie, but it'ts the same horror-scene on repeate, over and over again, just slightly modified. There are absolutley no Sci-Fi in this movie at all, just false marketing to connect it to the sci-fi genre.

Watch the start of the movie, like first 15 minutes, then jump to the end, skip the hour in between. This should have been a 20 minutes short but are running on fumes for eons.

There are absolutley no plot-twists at all, the movie are totally predictable, it's easy to tell who are the redshirt, who will get laid, who will jump out of the window and so on.

There are no need to even start talking about the ending, it's so predictable.
