It is already sending negative signals with a boring start. It continues with ridiculous dialogues of unlikable characters. The acting is far from convincing
When they have an accident with the car, the girl keeps shouting with her shrill voice, but the young people chat unnecessarily instead of taking care of their friends. The most absurd part is that the girl first yells and then shoots a video to get likes on social media. Today's young people are in a terrible situation
When they encounter zombies inside the house, the movie moves a bit with effective music. They can't reach their friends and need help, but the young people prefer to have fun at the festival. Irresponsibly
The joy of the festival grounds is not felt. There's just the chaos of a zombie outbreak attacking people, with no clear origin or reason. The makeup and movement of the zombies could have been better.
It is hard to understand how the characters are friends. There is no trust in each other. No respect. No understanding. The selfish character Ash first wants to leave her brother and go to have fun, but then she tries to fight for her brother.
It's a pointless, but I'll give it an extra point out of respect for the effort.
