Other than a pregnant detective in labor, this show finally moved away from the annoying soap operas much of the season has suffered from and got to some more dedicated focus on the characters as police ... even if the premise of the episode seems rather silly.
There are simply too many jumps in logic for the "bad guys" and too many scenes that were written for effect rather than to hang together with other scenes ... for example the bad guys coming after the first two LEOs with guns, but the merc doesn't have one when he attacks Nolan? And later the gang of disgruntled crooks have bulletproof plastic but only carry machetes and other hand weapons? Then our two heroes waste ALL their ammo on the shields and don't lower their aim for the legs? (I'm not the first viewer to mention that one LOL).
I hadn't been keeping track, but I mentioned somewhere in the middle of the show that it must be the season ender, which my wife quickly confirmed.
So while I had fewer things to roll my eyes at than other episodes this season, the plotting was still amateur level writing. The first three seasons of this show were great. It started to slip a bit in season four, and five has been a disaster.
However, I see it's already been renewed for season six, despite viewership being rather low at about 2.5 million per show ... but that's not too unusual in the current climate of a zillion useless cable networks and "original" programming on services such as Netflix and Amazon Prime and Apple TV and Hallmark and GFC and HBO ... etc. Etc. Etc.
