If you can get past the lack of special effects and other technology we have today; it's a great sci fi movie. For those of you haters trying to get this movie banned or shaming others for liking it by saying it is an all-white cast - I challenge you to truly watch the movie. One of the leading roles is of color!
That being stated: smart people learn from their mistakes, careful not to repeat them. Really smart people learn from mistakes other have made. While the rest become bitter, using errors of the past as a crutch and rob themselves of happiness.
Be happy, my friends and I hope you enjoy the good old flick...I have called wrinkles as cracks since seeing this movie.
