Watched Horror in the High Desert last night (based on recommendations from right here in this thread), and it was...well, it was worth watching. I didn't tell my wife it was fake, and she didn't truly catch on until the reveal near the end, although she was very suspicious. I thought for sure when the news report came on, she'd catch it (I mean I saw the 1-800-555 number on the scroll and thought they weren't even trying anymore), but she missed that or it just didn't register. Everything was pretty good and believable (as a documentary, not as a story) except the PI and the police involvement. She watches a lot of crime docs, and worked with LE for a good 15 years, so it's hard to pull one over on her - luckily they only obliquely referenced the police side of things, but the PI she was onto immediately. Also I had to cover for the movie when the 'sister erased the video,' cause even she, an internet normie, was like that's not freaking possible (I told her yeah, wait, there's more to it).
All in all it was good, and even fun if you're watching it with someone who isn't in on it, but for me the biggest let down is what it builds up to. It just seems like the dumbest option of everything available, especially if you're going to show that much of it. The wife, who was kind of forcing herself to play along by then, immediately goes 'Oh, it's a joke.'
Anyway, I still think it was well done (other than the end). There was a lot of subtlety in it, making the sister an overly dramatic shitbag, the roommate being a little sus (although they should've done a bit more with him, they built up suspicion a tiny bit, and then immediately said he had nothing to do with it). Basically everyone was good in it, especially the sister (by being almost exactly like the kind of human garbage you'd see in a real doc) - even the PI was fine, it was just off in the way they brought him in/the info he gave was all off for people that deal with that kind of stuff, but that's a pretty rare and minor gripe.
2.5 stars, check it out if you can find someone ignorant to watch it with.
(Also if you watch it on Prime, don't pause it cause it pops up the actors names with their characters if they are on screen - almost spilled the beans for me in the first ten minutes).
