Not just because of that theme in the movie. Which was one of the lame excuses for something reminiscent of plot. No.
I watched this, knowing I would not like it. I HATE numerology. Whenever someone starts going off about patterns with numbers I feel the urge to slap them. My own brain starts hurting out of empathy. And fully aware this is a movie just about that topic, I couldn't resist the urge to watch it and maybe get a good laugh. But it wasn't funny. Just exactly the dumb sort of "Isn't this totally scary and yet amazingly cool?! I can turn any crap into 23!" dialog I was afraid of. As soon as the son started to chime in, I knew this movie is a turd, no matter what happens. But I hardly ever stop watching a movie I started. I sat through it. I enjoy the pain.
The movie pretends to mock numerology under the disguise of showing how obsession can end badly. But it rides that wave as much as it's supposed to crush it. I don't see that message. I only see characters raving about a stupid number with little plot to justify.
Top that off with the usual "surprises" - trying to put another twist to throw you off, that makes no sense, and you almost believe it due to the quality of the narration up to there - and you get one hollow piece of movie-making. That just happens to be centered around the topic I despise. If only it did not try to be serious and rather had been some hilarious movie with actors I don't give a damn about. But I was starting to like Carrey...while it's not his fault, he is trying. It's not even good for watching with a bunch of friends and mst3k the hell out of it.
My expectations were low enough for someone to trip on them, but this movie managed to live up to be one of the worst I've ever seen.
