1) You have time travel and when you can go back to the past you should have tried to find a solution rather than drafting random people to fight a lost cause in the future.
2) They say they are sending people who have already died in the future to avoid a paradox. Since only 500k people are left then whats the point in restricting people?
Almost everyone out of 7 billion folks are dead.
3) So you can drop into a swimming pool from hundreds of feet and still survive.
4) No one's alive in Miami and they have the lab there. I think they should have prioritized the evacuation of the lab rather than the bombing. The aliens don't have any AA capability so its not a time constraint for the F22s to wait for a bit before dropping bombs.
5) They have a toxin to kill male aliens but not the queen. Why not use that only to reduce the number of combatants for the time being.
6) Why didn't they blow up the queen when the male aliens attack?
7) And seriously we have radar that can detect aircrafts hunders of Kms away and sonar has further reach than that. Nobody had any advance warning that the male aliens were attacking?
I mean WTF!!!!!!!!!
8) When Muri falls off to her death Dan jumps after her knowing that he is the only person who has the toxin to kill the aliens and what was his plan in case he caught her? As both of them would anyways fall to their deaths
9) Only Americans could figure out that the aliens didn't land in 2048 but they may have been there from the beginning
10)The random school kid can figure out from a claw where the aliens came from.
11) They find the alien ship and instead of taking photos and coming back to the govt. which would then nuke these buggers they try to handle it on their own.
12) They have explosives to blow up the ship but still they go around jabbing each alien individually.
13) If you gotta jab then why don't you jab the queen first?
14) Then the final blow to my brain cells. You kill a alien which needs hundreds of rounds to kill with melee attacks. That too your guns have no recoil and don't need to be reloaded.
