Average, but then again "Just Average" is a big step up from where the show has been. There are no scenes of people whining about characters no longer in the show, no moping or sappy schlock...
Instead we got a basic investigation that would logically be handled by NCIS, rather than some rando outside crime that is at-best tangentially related to the Navy.
Funny thing about blanks... it's not even the paper, but just the concussive force of the blast that can kill. The number of actors who have accidentally killed themselves by playing with guns loaded with blanks thinking that they were safe is... Depressing. Almost as bad as the number of parents that let their kids vape or use e-cigarettes because they think "Safer" is the same thing as "Safe."
