I have to admit, I wasn't the biggest fan of Signal - a movie that made quite the waves many years ago. Don't get me wrong, it's not that I didn't like it, I was just not as fond of it as many others were back then. Having said that, I imagine fans of that movie will like this too.
One thing you have to keep in mind here: the movie gives you more questions than answers. Also it provides ... well some answers in pieces - you have to put them together. So the main character is doing this - that should mean that this happened in between, right? And what about that character? Saying certain things, but is he telling the truth? Also what are those noises from upstairs? Again - this warrants multiple viewings and even then I doubt you'll be able or fully satisfied.
