Thought this movie had a fun premise, but it pretty much face dives off a cliff midway when one of the characters decides to kill himself for the sake of his experiment. See, I don't really think the movie justifies this. Not for two doctors who seem scientifically inclined. The doctor who kills himself is shown to have a pretty good life, however this little stint into the supernatural quickly convinces him that suicide is the only answer to move forward? I have a hard time buying that and don't think the suicide scene was earned at all. There's a sequence where one of the doctors' mother dies where he is thinking to himself "The human brain can go 3 minutes without oxygen" which is supposed to be set up for the audience to know that the movie is going to temporarily kill a character and resuscitate them (the movie actually does this at the end), but two supposed geniuses aren't smart enough to try this before resorting to the nuclear option? Just based on this, the two characters are ruined, coz if I can think about trying this, there's no way they couldn't have. This is even shown to be effective...

Now, after that mess of an occurrence, the movie follows the surviving doctor as he further gets consumed by the experiment, probably blaming himself for his dumbass partner's suicide as well. This genius also decides to kill himself which would render his partner's sacrifice moot, but gets saved by the ghost of his dead buddy. Lucky that that's how things work in this universe. So now you have this guy communicating with a ghost in the afterlife who's supposed to have the same goals as him, but that is not once realized in that final part of the movie. Basically, all the ghost uses him for is typing up loose ends caused by him spontaneously taking a bullet to the brain. Then the ghost's character flips and starts trying to murder him only to flip once again after choking him to death, to resuscitate him. So, maybe I missed the motivations completely and perhaps there's some afterlife fuckery going on which makes ghosts act differently, but I really don't see a compelling throughline here. I'm assuming the message the ghost wants to put across is to not let your life be consumed by something to that extent, which I couldn't take seriously enough given who the message was coming from (both, this movie and the dead doctor). If he really did only want what's best for his friend, maybe he shouldn't have possessed his corpse, bent his leg in four different ways and thrown him down a stairwell (lucky he didn't die there. That chandelier looked like it was supposed to land on him).

Besides this, I still take some issue with this movie's approach to ghosts being that easy to find. I mean, easy enough to just assume "this is how it must work" and then that is how it works, for every hypothesis. It's a pretty juvenile premise, but I guess I can grant it that for the sake of the underlying story. Too bad, I didn't really find much worth in that story. What I think is missing here, is the factor that changes the dead doctor's motivations post suicide, which the story wants to assert is that he deeply regrets killing himself and doesn't want his friend to see the same end. You want me to believe that his drive to further his experiment was strong enough to prompt suicide but not strong enough to actually help further that experiment coz of the regret of leaving behind his family and loved ones? Yeah, there's some missing character development at some point in here that just disconnects me from these characters.
