Social commentary that isn't far fetched. A small amount of negative imdb commentors project themselves into the situation and get frustrated. I don't understand them getting annoying by comparing what is basically a slasher with chavs, to ones own survival fantasy and logic. Logic in a fictional movie? This movie isn't even meant to be a real story, it's meant to have realism to it. Somehow this confuses people? The realism was the reflection of society within the characters. The story was illogical at times and simply moved us from A to B for entertainment and pace sake. I'd have liked a better story myself but it wasn't to be, and it wasn't the main motivation of the movie anyway. If you wanted a real story it would probably have been two people hiding in a bush for a very long time.
I think this movie just made people uncomfortable for some reason.
The ending made perfect sense for me because the main villain had himself played out a violent revenge fantasy . It left us with obvious answers about environment and upbringing, but also gave us some more questions about personal responsibility, morality, culture and ego.

It's sad that backwards horror characters, once an appropriate setting in dark places of the USA, are now well placed in Britain. The main good guy characters could have had a little more weight to them so we cared about them.

Now I went into this movie without any expectations, and without any clue as to what the story was about and now the only thing going through my head when the credits starting rolling was the pure and utter disappointment that this wasn't a movie about some kind of lake creature attacking unsuspecting sunbathers.

I'm severely disappointed by this, otherwise it wasn't a _bad_ movie, but I also wouldn't go as far to say that it was good. I feel that I'd have enjoyed this a lot more if I wasn't so good at guessing plot twists, but that's more of a me problem than a problem with the movie. The characters were strong and the acting was decent, there wasn't really much room for character development which I think actually works in the favour of this movie since I feel the director was trying to have as unlikable characters as possible, so that the audience hated them, I think that was the whole point. I will say there were a couple plot holes I noticed but nothing that really took away from the story.

Ultimately it was pretty enjoyable, I'd probably watch it again now that I know what it's about just to go through any other details that I might have missed whilst waiting for a lake monster that didn't appear.
