mate ; Kate Caldwell ( Naomie Harris ), a scientist who once worked for the Wydens ; and Jeffrey Dean Morgan , chewing more scenery than any of his monster co-stars as Harvey Russell , an agent of some ambiguous government branch . Morgan gets the movie ’ s best line , and maybe 2018 ’ s best line , the nuances of a very silly plot to an audience that is only here for the monster action . The monster b-movies of the ‘ 50s always had that one scene in which a scientist explained the plot to the square jawed hero and cantilever brassiere wearing heroine , but it seems like today ’ s mega budget equivalents give us one of those

Aside from a few knowing one-liners ,

Rampage never fully embraces the ridiculousness of its plot

when he introduces himself with this all-timer : “ When science shits the bed , I ’ m the guy they call to change the sheets !” Whichever of the four writers is responsible for that gem deserves to take home an Oscar next February . Sadly , it ’ s a standout line in an otherwise flat script that spends too much time tasking its characters with explaining scene every 10 minutes . When said monster action arrives , it ’ s initially quite impressive , with the giant trio wreaking havoc on Chicago , but then it descends into one of those generic modern blockbuster climaxes in which all the action takes place in a giant cloud of smoke , presumably to save the FX crew the hassle of rendering a city .
