I've enjoyed the first two episodes, and credit much of that to the chemistry among the actors. As some have commented, this reminds me (fondly) of Burn Notice. I'm not looking for anything deep or intensely meaningful, so this is just fine. But allow me to nerd out just for a bit.
I can accept a significant amount of suspension of belief in the name of entertaining fiction, but gratuitous nonsense irks. I’ve always suspected that one to culprits for our relative STEM ignorance is the false presentation of simple scientific principles in popular entertainment. For example, Superman cannot lift thin-skinned aluminum-hulled airplane by the palm of his hand. The force needed to move a many-ton aircraft exerted over the small surface area of a hand (Kryptonian or otherwise) would punch a hole in that hull as easily as a pin goes through a balloon.
Here, we have a safe with two people trapped inside that “fills” with water within seconds. Anyone who’s filled a bathtub - and knows how long that takes – knows this is absurd. While we don’t have the flow rate for the burst pipe or exact measurements of the interior of the safe, we can do some rough calculations. Let’s estimate the flow rate at 5.5 gallons a minute, which Google tells me a good estimate for the average flow rate of bath tub faucet. While we also cannot directly connect the flow rate of the busted water pipe to the average flow rate of a bath tub faucet, the flow rate of that busted pipe didn’t really look like a raging torrent – so bathroom tub faucet it is. Let’s estimate the safe as a cube 10’ by 10’ by 10.’ That comes from the unhelpful instruction to “stand back 20 feet” from the explosion and the response, “well, we only have 10” or something similar.
So how long would should it have taken to fill the safe? One cubic foot holds 7.48 gallons of water. Ten by 10 by 10 is 1000 cubic feet. Let’s subtract 6 cubic feet for stuff in the safe (the two people – average about 2.5 cubic feet in volume - and the table). 994 cubic feet should hold about 7450 gallons of water (996 x 7.48). At 5.5 gallons/minute, the fill time should be 1354.56 minutes (7450/5.5), or 1.5 hours short of an entire day. This also assumes a constant flow rate, but the point is 22 ½ hours is vastly different than a few seconds. Even in escapist, fluffy fiction, we should be able to do better than this.
