Once again, the ignorance of the writers on the body of knowledge is shown... The writers seem to just not get the fact that their knowledge is so limited that their writing is poor in dialog and not well-thought-out.
There are so many movies with proper military tactics that this episode is just ridiculous on so many levels.
And the haphazard medical procedures and the escape tactics - ridiculous.
Body bags if not fully zipped are not air-tight and therefore cannot be used as airbag because the explosive pressure from the fire extinguisher will open the zipper. Result: Mac and Jack will perish.
A watcher for a target will have a backup on the other side of the house and will not use a sniper rifle. They will be mobile. So therefore, this premise is false. Result: Mac and Jack will perish.
An open gun-shot-wound creates pneumothorax which prevents breathing. Especially if the lung is punctured. You need to vacate the air. Result: The accountant will perish.
Smoke bomb - would make the car fill with smoke so Jack would not be able to drive. Result: Mac, Jack and the accountant will perish.
Surgery requires a sterile field: this means sterile air or at least non-moving air so pathogens and crap do not enter an open wound. Result: accountant will perish in the back of the SUV.
Suction of the hemothorax does not require significant extraction of blood - just like 1 pint: while Mac is avoiding sucking out the blood with his mouth, the patient will perish of cardiac arrest.
Money laundering site hacked in Malaysia: These places are low tech so they cannot be hacked. Result: Riley fails. Mac, Jack, accountant and Riley will perish.
The Medical Examiner van is easily spotted by trained mercenaries so following them is impossible in the Medical Examiner van. Result: Riley, Mac, Jack and the accountant will perish.
Throughout, they are using inner-ear-communicators which require a tower to relay from. They are not in the US so they need to have a base station or they need to be within 33 meters of each other and reception is very poor. Their current communications should have been much more faulty. Result: All will perish.
Satellite phones give up location. The mercenaries should have found them easily. Result: all will perish.
Freon poisoning for Mac: requires oxygen after exposure in a hospital and sometimes gastric lavage. The skin would have been burned. Result: Mac will perish en route to the exfiltration.
Insulin levels increase with beta-blockers. This is what reduces blood glucose. So during simulated death, Mac adds insulin (glucose antagonist) with glucose. Result: nothing and the accountant will perish.
Security systems running on wifi: security systems run on their own cellular network in remote areas. They do not run on wifi. Disrupting the wifi to get the security code would not have worked. Result: local police would have been called. All will perish.
Identifying target location based on shell corporation: specially trained mercenaries would be too smart to set up a local company when targeting a site. Result: all folks in Miami will perish.
Realtime translation is represented as too fast: the uplink from an area as remote as the one shown would take a lot longer to translate. Result: the accountant will perish.
Realtime text-to-speech is not as accurate as depicted - between 50% to 75% without specialized software. Result - the accountant will perish.
The dialog is stilted and just not funny. The accountant's whining gets old too fast - no one would continue to act that way with their life in danger except and idiot and that idiot would not be a financial genius. Financing requires a level of shmoozing not evident.
The team just doesn't gel in their actions - MacGyver should be communicating with his teammates on what he is doing before they have to ask. They are a team. This is not Doctor Who where everyone else is MacGyver's sidekick.
The level of interaction shown with Riley and Mac's roommate is extraneous - either develop it or leave it alone. The level shown is just used as an expedient segue.
Patty Thornton walking into the room just as communication is needed - not valid. Patty Thornton would be monitoring as do all ops leads.
As you can see, the writing has not gotten any better and the tech research is getting worse, as is the knowledge of military and special ops tactics.
Please hire me or someone decent to do this work and stop spoiling the icon that MacGyver is. At least go watch some James Bond or some Scorpion or something. Stop being so proud that your ignorance shines through and your series doesn't get to season 2.
I understand that Millenials think they know everything. But this is crazy. Knowledge is power. Experience is wisdom. Humility is success. Admit what you do not know and learn through others that have the first. This is the first step in your real growth into future writing icons.
