The storyline is full of plot holes and nonsense. Very disappointing, probably one of the worst movies I've seen this year. Many problems arise out of thin air without giving a proper or plausible backstory to explain what caused them. All problems are solved so quickly and stupidly. Second, the villains and horror elements are stereotyped. A lot of killing and violence is unnecessary. The way the characters are killed is so stupid. Sci-fi elements are outdated. Many jokes and plots are derivative, immature and predictable. The props are designed primarily for aesthetic purposes. The jump scares are so pointless. I could go on for a few more pages, but I just want to say that this movie isn't worth watching because despite its amazing and exceptional CGI effects, the storyline is a mess.
Even the key ideas or messages of the movie are portrayed so badly because so many unnecessary scenes are added just for cool effects.
