Well, you sure haven't seen a movie set in this setting before, but the movie is going over fairly standard plot points. Because of the setting though, it adds a creepiness factor that makes it entertaining to watch. It does take a while to get to the house, which is annoying, but once there, it really starts to crank up the creepy in all the right ways.

Not a bad film. Wife liked it more than me

Well, I liked this movie. It did well creating a claustrophobic atmosphere, and creepy environment. Story was OK too, and although the Blair Witch-style camera work may not appeal to all, it does add to the authenticity.

I was kinda skeptical before watching, I mean the premise is kinda stupid but also intriguing. As a fan of found footage and movies that don't particularly follow the basic path, I found this quite enjoyable. It sure has some flaws and could be even great if they had focused on other things and used the new environment a little better, but I found myself sometimes scared, had a dreadful feeling while watching it and was totally surprised by the ending. Consequent and bold. I love it. I think it deserves some recognition, therefore I will give an extra point because I have never seen something like that.

The underwater photography is good (though disorientating) and the movie's concept is a good one.But with a weak script and irritating characters, this is a movie best left to sink without trace.

It was an ok POV haunted house movie. But the excessive amount of bubbles and shaking camera really made it hard to see what was going on sometimes.

The Urbex-diving idea is interesting, but the whole movie is definitely poor.

basically watched this from comments and found it a good watch

It is good at some points, but after they go underwater and this start to happen you can barely tell what's going on.

It didn't quite hit the landing, but as a fan of claustrophobic horror the build up there were very much worth watching.

Straightforward scary movie set in a very creative environment. As some real tense moments and the underwater works well but also use to many vulgar horror cliché making it an average movie

The concept is so unique, that makes the entire film very watchable and solid.

I enjoyed this movie quite a bit, the setting and atmosphere were very well set out.
You did have to put a few things together yourself (which seems to have been missed by other reviewers here) b ut it's all there for you if you actually watch it.
The lead male is exceptionally unlikable and you may find you want to see his demise and the lead female I would like to see more of in horror movies as she made a great scream queen in this.
Watch to the very end for a post credit scene (maybe 3 seconds max).

This was an ok movie.

Like when someone drops your plate of spaghetti on the carpet and scrapes it back into your plate with the blade of their hand and then still gives it to you.

It takes forever to get started and that sucks because the lead male character was such an asshole, I was in a hurry to see bad things happen to him. Then, to make it even worser, the camera work is so sloppy, you can't enjoy watching it either, as it renders the film as scary as an unflushed toilet.

Overall, the movie had a lot of potential. The idea is an interesting one and the actual setting was pleasantly creepy. However, unfortunately, it just mostly falls flat. Nothing really made sense. Not everything has to be spoon fed to the audience but usually we like some sort of explanation or reasoning behind what's going on. It felt like the filmmakers had a good idea for a big twist but once they reached that twist they had no idea what to do next and just defaulted to pretty generic stuff. The main actress wasn't bad but her boyfriend just wasn't a good actor.

Love the concept but the execution just wasn't there.

Filming underwater with a limited budget is obviously not easy so I can sort of understand that the elevator pitch of "it's a haunted house BUT it plays at the bottom of a lake" didn't really result in a great movie but I didn't expect them to also fail so miserably at the writing portion. The dialogue felt stiff like it was dubbed into English having me not invested in the couple at all and the they didn't really know what to do with their runtime after the initial exploration of the place and even forcing exposition for the "climax".
I did like how the set looked submerged though but I can't say that it felt very claustrophobic since the camera still made things look oddly sterile. Maybe they should have just stuck to the POV/drone cam so they could do things besides the jumpscares [spoiler](the rotating shots do however not boost my confidence in that)[/spoiler]?
À l'intérieur remains a fluke sadly :(.

Terrible movie where both characters day, and little to no explanation as to why they were brought and baited there and as to why there are even enemies present.

a little bit creepy but mostly just a whole lot of unexplained nonsense. like why are some chairs floating around but the phone's chilling in place? i couldn't focus on anything after that point. ending was frustrating too, so it lacked the payoff that b rate horrors usually have.

It's a cool concept and must've been a bitch to shoot.

Nothing to see here, guys. Very boring movie!!
