this movie start off well . when the guy come to the main character base with that scrool then he be chop up by the screamer . the plot also start of well . little ground digging ( like miniature version of those thing in tremor ) robot be use for war and and guy on the same side a them wear wrist band that let the screamer know they be of the same side . the people in the base have to smoke some red cigarette to protect their lung from something in the air we have to protect our lung from sht by put sht in them . but this movie get bad in a hurry . we really want to turn it off when those kid ( screamer in kid body ) be walk and the main character go help me . but some decent special effect and ok atmostphere let me give this film 6/10 .
