“Top Gunner” (*1/2 out of four) was a stale, synthetic action melodrama about a group of renegade pilots (Buck Burns, Julian Cavett, Reavis Dorsey) from the U.S. Air Force who have to protect a biological weapon from falling into the wrong hands of the Russian military who want to seize it any costs. Result is such an obvious rip off of “Top Gun” (right down to its title, no kidding) but it also rips off “Iron Eagle” and also “Red Dawn” to make it feel like a KMart greatest hits of ’80’s action fare. Eric Roberts sneers his way through a token role as the group’s tough but tender instructor.
