Corrected entry: Regarding the radios used at the Biosyn facility. They are Motorola Talkabout FRS/GMRS radios that one can buy for ~$50 at a department store. There are many problems here (range limitations, licensing, etc), but all those aside, it is inconceivable that a company like Biosyn, after having spent potentially hundreds of millions of dollars (if not more) on top of the line infrastructure, would base a critical communications network on cheap consumer grade walkie-talkies.
Corrected entry: When Charlotte Lockwood is doing a vlog holding baby Maisie, the needle she uses pokes Maisie's leg twice, which couldn't happen in real life.
Correction: I'm sorry... what? First off, I'm genuinely confused what you mean by saying that poking someone with a needle twice "couldn't happen in real life." Poking someone twice with a needle is absolutely possible. It's literally happened to me when I've gotten blood work done and they can't find my vein. Second, she doesn't actually poke her twice... she just shifted her hand, which made the needle kind of move back and forth for a second. This mistake makes literally no sense.
Correction: Big companies buy cheap stuff all the time. This movie had a budget of well over a hundred million dollars and the studio literally used those radios as props. So it is conceivable that a fictional billion dollar entertainment park / science sales project would use ordinary, commercial radio systems.
