Mmm, like how the trailers for this were saying stuff like "its all been leading to this! All the activity has lead to this! dum dum dum!" etc
It all just reminded me of how Saw IV, V and VI were promoted. They all said things like "answers are revealed! Discover the truth" and so on. Of course you never did, and there was always another film to come. It wasn't until they finally stopped with VII that they (more or less) paid things off.
But yeah, given what was revealed about the demon, the cult behind it, the girl's grandma etc in the third movie, very little is followed up on or explained in this new entry.
There's also a definate suspension of disbelief in the final part. How is Alex recording this? Presumably on her iPhone I guess. Would you really be running away from monsters trying to kill you and still be holding up your phone to record it all?? Ha
Some other points I wanted to make on the movie that I'll use spoiler code for-
So this takes place five years after PA 1&2. at first you think the creepy kid over the road is Hunter, but then it turns out the kid of the family is actually Hunter, who was adopted a few years ago. So if Demon-Katie took Hunter away as a baby, how did she lose him in order for him to be adopted? It seemed like the point of the movie's events was like her trying to get him back, but she already had him anyway at the end of PA2. I didn't really understand that.
And then also, so who even was that creepy kid over the road? Katie's son? Where did he come from?
And who were all those dozens of possessed people/demons (like how Katie looked) at the end? Gah, I need answers! Don't want to have to wait a whole other year for PA5 and then that probably won't explain much either.
Still, that part where demon-Katie was at the end of the corridor and then like RAN down it after Alex with that horrible face scared the shit out of me
An amusing point though, it seems in these movies if you're the male husband/partner/boyfriend it's doubtful you're gonna survive till the end! Micah in the first, husband Dan in 2, boyfriend Dennis in 3, and now friend/boyfriend Ben in 4
