very interesting . the big twist wasn not as big a shock a maybe they have hop for and it be very dated but it do get my mind work . it really get me think about a world without vegetation or livestock and make me appreciate the world i live in a lot more . charlton heston do a good job and a do all the support character and and it be a very realistic film which be surprise . it lack direction at time and a lot of the setting and background need more explanation but it be still a surprisingly good and intelligent movie . the main fault that i could find be that i do not want the film to end when it do and i would have like to see what happen next . positive .
