THE BUTTERFLY EFFECT is actually a branch of the Chaos Theory. What's the Chaos Theory...long story short, it practically says we can't predict the future. Why not? That's where THE BUTTERFLY EFFECT comes in. The Butterfly Effect states that: Because of the constant choices and every little thing we can, could, and could've done, we can't predict the future. If you breathed, "HUFF, HUFF, HUFF" WAIT!!! What if he held it? "HUFF...HUFF" Any small change can change the future in the most drastic ways. As this movie shows. This movie has good role models: "No one could possibly love anyone as much as I love you,” Evan(Ashton Kutcher) tells his true love Kayleigh(Amy Smart) sometime in the movie. And his actions largely back up the statement. He even makes the biggest sacrifice-which may also be the most heart-wrenching ending ever- in romance movie history. This movie also shows how much children need a father figure. Now, that wouldn't be much even WITHOUT the bad stuff. So imagine it WITH the bad stuff. Violence. Now, I LOVE violence not much gets me by as "brutal"(only one scene from Kick-A**-the captured, public execution scene). Not unless it's EXTREMELY intense. The scene with the dog was sick, twisted, demented and just f*cked up, pardon my French. When he hit the girl with the, what I'm guessing was a, 5"x 6" piece of wood, you hear a loud "CRACK!" I felt like I was the one who did that! The most brutal scene, though, was, I'm sad to say, my favorite violent scene. I just love comeuppances-when d-bags get whats coming to them- and I was waiting a while but when Evan started beating that guy with the titanium bat, I just loved it! Every second. I know that sounds demented and sick, but-HEY! The little twerp had it coming! He burned the dude's f-ing dog! Sexual. Nudity. Explicit sex scenes. And don't forget the whole child molestation and pedophile thing! Twisted, vile, and just plain EVIL! Like was that REALLY necessary?!?! Negative Role Models. The little evil brother is abusive, foul-mouthed, short-tempered, and just a total jerk! But it is viewed as negative. More a romance than a thriller in retrospect. The alternate ending...SUCKS NUTCRACKERS!!!!! Good movie all-in-all. I know everybody makes it seem so bad. The worst is the violence. A bunch of brutal for me, so...REALLY BAD 4 U! The nudity I hate! I have a strong moral stance against nudity! But all-in-all: breathtaking and incredible feat in motion pictures. The strangest of all? This movie is based off a children's book.
