A good film to watch. I would ignore the negative reviews but then everyone has different tastes. Yes, things go wrong and it's great to see a movie where you would do things differently if you were one of the characters.
It is a good watch, it is not going to be your favourite movie ever but it's a GOOD watch. I like it the style and characters. Some dark humour too and it really is like a film where you will go "oh no, they shouldn't have done that". Also for those go walking and hiking, it's great to remind of you what NOT to do. Overall, it really is a good film and worth a watch for sure.
