First, in all fairness, I haven't seen this movie. Why? I refuse to watch so called horror films that demonize snakes. Snakes are NOT evil, people, they are part of nature, and maybe occasionally one will eat a person. But we eat cows, spiders eat flies, and so on. Snakes are lovely creatures, and the CGI never does justice to their beauty.Anyway, my main problem with this movie? The cover. 'Boa' it says. OK, Boa Constrictor. The people behind this movie obviously did not do their homework on Boa Constrictors. Their teeth do not sit up front like venomous fangs. They sit in back, curved backwards, which is why a bite from a Boa would be painful.In conclusion, please, do not make more movies demonizing animals. Make movies about monsters that may or may not exist, make movies about humans who are monsters inside, but don't make something innocent evil. And if you MUST, do your homework on the creature and make it look realistic.
