If you think his name, he will come and screw up your life. If you say his name, he will come up and screw up your life. If you see this movie, it will screw up your life. So save yourself and don't go see this movie.
I have never liked the premise of this movie. It's so stupid. You have this "spirit" that if you think or say his name, he will haunt you and make you do unthinkable things. If you say his name to other people, those people now have the potential to be effected by The Bye Bye Man. However you can stop him by not thinking/saying his name.
If you really think about it, The Bye Bye Man is basically just a virus. The only way it can flourish is by the faults of other people. When you introduce the name of The Bye Bye Man to other people, they can't think of it or else their life will get screwed up, then they can spread it to others. I don't want the villain of my movie to be a stupid virus. I want the villain to be someone/something that is actually intimidating. Not a dumb virus.
If you are clueless enough to see this movie (really, don't see this movie) you will see some of the worst acting you will ever see in a theatrical motion picture. They are just so bad. You will never be able to take them seriously. The main actress Cressida Bonas could not deliver one good line even if her life depended on it. You are not supposed to laugh unintentionally while watching a horror movie, but Bonas will make you life with the beyond horrendous performance she gives us. The other two leads Douglass Smith and Lucien Laviscount aren't as bad as Bonas, but they are still pretty terrible.
To sum it up, this movie seems like it was trying to hard. The acting was terrible. The premise is stupid. There are so many moments that make you think "This must be one of the stupidest movies I have ever seen."
If I was in charge for putting one quote on the movie poster, that quote would be "This movie is full of stupid."
The Bye Bye Man rightfully deserves a 2/5
Probably the stupidest part of the movie came when the main character was browsing the computer in a library. He was researching The Bye Bye Man. He didn't go to google.com to do it. He didn't go to yahoo.com to do it. He didn't even go to bing.com to do it. He went to search.com. This movie couldn't even afford to put a name brand search engine in their movie for literally 2 seconds!
