Why did Gail send Colt on that wild goose chase? if she wanted to frame him, by sending him to Tom's apartment, why was Iggy there, why weren't the goons there to grab him immediately? Iggy being there, and telling Colt about the drug guy was apparently unexpected. yet the drug guy still knew about the hotel room, sent colt there... but also tried to bag him.. what was the fruit platter nonsense? the hotel guy seemed to know about the ice..
The cops role in everything. major terrorist actions in public. no cops any where. Colt reports the dead body.. but is announced as the prime suspect on the news? cgi deep fakes can be identified. particularly if the accusation is made. they really wouldn't need a "confession" which really would not hold up in court. at best that just implicated Gail as well.
bad guys were just Toms private security crew presumably. I don't think it really needed to be explained. but sure one or two lines to say it would have helped.
sneaking back onto set is reasonable. but, the security crew showing up, "taking over", but then just vanishing so the guys could get back to work was weak.
Shooting a phone would not necessarily destroy its data. they already established Venti as a "tech genius". they didnt even bring it up to try. never mind questions of cloud storage, forwarding, etc. had to chromecast the video to a TV to watch in the first place.. so they aren't completely tech illiterate. this isn't a plot whole, more of a gap or contrivance. people aren't perfectly logical and do overlook simple solutions often. but, having others point it out also is an easy joke later. Maybe thats part of the extended cut. Venti gets her hands on the shot phone, or cloud data, and calls the police/sends it over to them. and that explains why they show up at the end.. Which leads into..
why do the cops show up at the end? they show up in force to arrest tom, gail, and her men. but the show is operating on the logic they think Colt is guilty.. and dead. they haven't seen the confession, from 10 seconds earlier. so for that force to show up, they must already know tom, gail, and the men are guilty.
