Unfortunately, when I decide to watch this style of movie, of supposed suspense involving animals or creatures of various sorts, I do so expecting all the worst. It has become the norm, a pretty poor result to watch, but going in with that foresight allows me to enjoy it as a comedic film hahaha maybe that's a bit rude to say, but in the end there are different ways to enjoy something.
Of course, that's a personal perspective and doesn't justify the movie not living up to the hype. On the other hand, in case it is good, I end up being really surprised.
Hahaha congrats on watching it all despite enjoying practically nothing, I'll keep it in mind for sometime when I have time left over to see how bad something can get hahaha.
May I ask why are you writing in Spanish? just out of curiosity.
