MC will shoot lackeys immediately, but spends 3 years talking before shooting important enemies (and getting stopped every time). Even after he becomes stronger, he's still a bitch. There's also various plot holes. Terror Man is a somewhat fun concept, but is average at best when it comes to the execution, due to the poor writing of the protagonist and antagonists, all of whom have plot armor and cannot die.
7/10 decent read, but Lilya should've been the MC.
