As someone who has watched a lot of horror/thriller movies, this one is not that impressive. The whole plot is predictable till the end. And not to mention the time paradox thing.
The ending is kinda meh. It's a good idea but hard to execute.
The acting is good though. There are many Korean horror movies that are much better than this one.
The Call is enjoyable to watch once, but I wouldn't watch it again.
