Could It Happen? Spoilers!SPOILERS!!!! !!!!!!!!!!!!
I have to say I have avoided this film because I don't like all but one (Sixth Sense) of the directors other films, but I watched it last night and thought it was good. Good mainly because I liked the idea.
The part where that character talks about tomato plants releasing a chemical to attract wasps that eat the aphids made me think about what other things plants might be capable of.
If plants and trees really were capable of communicating with each other then I am sure they wouldn't want humans to even exist, considering what we have done to the planet. So maybe we should feel lucky that all the plants and trees aren't capable of wiping us out like in this film. We would be in a no win situation if we had to destroy all the trees and plants if they "waged war" on us.
