"Showtime" is a step down for DeNiro, Murphy, and Russo as it stomps clumsily through its story about an all business detective (DeNiro) and an hammy wannabe actor uniform street cop (Murphy) who become the centerpieces of a reality TV show of the title name and a criminal investigation involving a sort of super gun. The flick has all the usual Hollywood action (stunts, chases, pyro, shootouts, etc.) with some Murphy signature silliness and a taste of drama thrown together to make a mediocre but entertaining no-brainer flick which is best served with a bag or chips, some dip, and a sixer. Save for broadcast, turn off brain, and enjoy. (C+)
