this movie be okay but severely mar by unbelievable human behavior and concept . rating 4/10as a science fiction fan and i can easily suspend disbelief about various scientific concept ( ie represent intelligently evolve ape travel back in time and conceive a child ( chimp ) and force field door and etc . ) however and when various common sense concept and human behavior be flaw it usually ruin the movie for me . just a few example from this film representspoilers concept represent how do ape change so drastically in such a short period of time and to become big and more intelligent in a mere 20 year . this be not even allude to in any way . have they make reference to or allude to bio engineering and or the virus have kill all cat and dog cause this and perhaps i would have find it acceptable and however they do not explain this even in the slightest . mere selective breeding would not permit such rapid change in 20 year . since we already have some understanding of evolution and such rapid development should have be explain ( if only in a single sentence ) . note represent since we have no understanding of backward time travel and it do not need to be explain . human behavior represent why and know what corneilus and zira tell them about the future and would mankind and human government permit the keep of ape a pet and eventual slave and while increase their intelligence and capability . i could see if this happen a hundred or more year down the road and but 20 year after the intelligent ape arrive from the future and tell how apes rule the planet and subjagate human and mankind be purposely make ape more intelligent and capable . it absurd . concept or behavior represent with such an oppressive and militaristic 1984esque government and how be they so easily overrun by ape and which seem to have their every move watch except for their collection of an arsenal of weapon . in a similar vein and how be it that such a society have a system in which ape take simple note of paper to business to retrieve thing for their owner ( include a firearm and amunition . ) a science fiction film do not need to explain every single concept and but for those thing which be not explain they need to make some degree of sense to our understanding of the way thing work and human being behave .
