I admit that I like found footage films, or, rather, I find that story telling device compelling. Assuming it's done well. To do it well, your film relies heavily on acting first, then editing, then sound They all work well here.
Too often, these sorts of films have actors who don't know what to say, or how to say it, as they are expected to improvise and aren't confident how to be "natural". In this film, the actors are brilliantly natural and their chemistry is superb. They are a very believable as a couple and as people.
The goal itself is interesting, as I have rarely watched a Bigfoot movie, so I found that part of the film at interesting spin. But really, the slow burn here is what really makes me like this movie.
As with other films in which the protagonist is a wannabe filmmaker, there are lots of establishing shots with the local townsfolk to talk up the legend, and to get a sense of what is to come. It's all done pretty realistically, and, again, the actors dialogue/exchanges with each other are especially convincing.
Again, this film is very much about the slow burn of tension. This is very much exemplified in a scene near the end that lasts nearly twenty minutes for one continuous shot. And it's not boring. At all. The actors are brilliant in the scene, as is the sound. It's a highly effective scene and you really begin to get into the same dread of what's next as the characters due to the immersive nature of the scene.
Overall, I really liked it. I think the director did a great job in choice/direction of actors, and the overall story was not over the top. It's a great example of how found-footage should be done.
Though, the film doesn't actually try to tell you it's found footage, it's just that the only point of view is the camera(s) used by the characters. But I'll assume someone found the footage in that fictional universe at some point.
