Spoilers!
This movie's run time is pretty quick, and it still felt quite slow. The idea that two people would go to the woods to camp, with literally no one around (minus the one "creepy" guy) is interesting that they reserved their camping spot. Starting out with constant foreshadowing, and basic things being avoided (taking a map for example).
The characters are a miss, and not believable. Later into the movie, Brad leaves his girlfriend's phone in her car, so they have no phones or map, or frankly any direction at all. They meet a fellow mate in the woods, and it plays off as "creepy" making you think he could be a threat. Yet, they see no one else while being there, minus when they first enter. Later, there are signs of a bear creeping around (breaking sticks, growling in the woods) but it still goes pretty slowly until it attacks, which is hilarious.
They wake up in the morning full well knowing a bear or bears are in the area (the broken sticks, the bear hole they find) but pay this no mind. Brad wakes up looking outside of the tent to see a huge black bear, and they just keep opening the tent to look, which invites it over. Jenn gets cut on her arm a bit, while Brad is literally mauled, and the bear spray does nothing (also takes her forever to think to use it). After, she gets out of the tent as Brad was pulled out and is literally dying, and when she finally decides to exit, she grabs the engagement ring?? After this, she leaves drinking river water (clearly don't do this) but they don't show it causing any issues except a quick cough. Later there is a scene where she outruns the bear to a cliff at a pre-described waterfall, and slips breaking her ankle. Making a slit with a stick she waddles away, and somehow looses the walking stick she had. Naturally she makes it back to the initial campsite, and collapses when she arrives back at the start where the Irish guy is with a tour and it cuts to black.
Overall thoughts was this was a hilarious movie. One basic thing to do when camping somewhere in the woods is to be prepared. Bring a map, bring food, bring defense (if known bear areas) etc. Literally of all this is thrown out the windows right away. Movie felt like a 2 hour film, not the short run time it had.
