Movie Big Ass Spider is a confusing mix of story typical for B rated movies and realisation that is not seen often in this category. This is Sci-Fi comedy that does its job and probably more. Story is unreal and simple. At some parts it are so ridiculous that becomes funny and it looks like that is the way things were supposed to happen. From secret military base alien spider escapes. It grows as it feeds and starts terrorising and tearing apart the city. After all available units and teams fail to kill the spider all bets are placed on clever exterminator Alex Mathis (Greg Grunberg). Alex is a character that will alone make audience laugh. He will receive help from team of scientists and on his mission there is one sidekick who will join him. Dialogs are well suited and funny. Sometimes they look like dark humor from real life. Because the spider grows with every meal, they have to kill it before it lays eggs. Legendary Rey Wise is starring as Major Braxton Tanner. Action, big ass alien spider, military cover up, scientist, stunning bombshells in bikinis and an unexpected hero are the elements of great Hollywood blockbusters. They are all present in this movie but this is probably satirical overview on cheaply filmed trash horrors and many Hollywood Sci-Fi actions.
