I know we're talking about a monster movie here but nothing anyone did or said made any sense.
For example, Hud asks Marlena what she saw as they approached the bridge, and the other girl said 'not right now..' - What!? The whole city getting trashed around you and it's a bad time to ask what it is?
Other things like walking down tunnel, beat off monsters, walk into med/evacuation centre, very handy. They also have a very understanding soldier who breaks protocol and helps them on their way, right in the middle of the biggest crisis ever.
This thing is vast, maybe 250' high, yet it manages to sneak up on them after they adjust themselves after surviving a helicopter crash!!?
Beth's tower block is trashed, so they go up the stairs in the adjacent block find a lovely little bridge, cross over, and happen right upon Beth's door, which they kick in and save her.
