I had the following questions about the first four hours of season 8 of 24:
1. why not just take a taxi to the handoff rather than make an injured man walk 5 blocks?
2. how did the Russian hitman join the NYPD in the space of a few months (or perhaps weeks)?
3. why did the evil brother believe the evil weapons dealer when he said his son had radiation poisoning?
4. why is evidence of radiation poisoning a solution to the problem of: "money or goods first?"?
5. exactly how does someone create a false identity good enough to join CTU?
6. why are personal phones permitted throughout CTU?
7. how do personal phones even work in CTU?
8. how is Jack supposed to go undercover when he was in nationally televised congressional hearings?
9. why exactly would you go to the trouble of bringing nuclear materials into the US only to export them again (of course, hard to have a threat against the US if you don't bring them in, so this is excusable)?
So far, the basic plot and premise are pretty fun and compelling: good Iranian stand-in, credible bomb threat to take targets out of secure locations, believable internecine conflict (who more likely to take over than the brother after a tragic death?), customary 24 expansion of crisis by adding in nuclear weapons dealing on US soil...
