Though I didn't care for it ... (Spoiler alert)

and this kind of horror, it does have a kind of value as, IMO, it does have a few very important life lessons one can glean from it
01. What not to do on a camping trip,
02. Learn crisis management and disaster recovery,
03. Choose your company wisely (you are the friends you keep, you may have to depend on them, ...) and more

So important, I'd otherwise give it a 5.
