Watched it last night... It made no sense... Hey, guy we meet randomly in the library, explain it! The ghost world got full, so now they're bubbling up into our world? Nope, that's a stupid theory. How does it even explain why people are killing themselves? Hey ghost, provide exposition to explain WTF has been going on in the movie! Oh, everyone is lonely, whether they're alive or dead, so we might as well just be dead? Sure, that makes sense. </sarcasm> And what's with all the damn red tape? Rarrr!
