There was so many things wrong with this movie, I don't know where to begin.
* What perfect, coincidental timing! No sooner had they just been to see the "expert" and learn that "soon things will be coming to an end, they're going to take some one" and it just so happens to be that very safe night - lucky they prepared for it that evening!
* After a few seconds Googling the strange goings-on (and googling via some random search engine, because no one uses Google in real life!), it turns out the first page you click on ALWAYS tells you exactly everything you need to know about the strangeness, with no further research required - AND!! for extra luckiness - the "expert" from said webpage just so happens to live in the same town as you, so you can go round for a visit! Phew! That's a relief!
* After literally uttering the words "we can't go to the police, they'll think we are crazy", the characters head straight on home to board up every window in the house - yeah, that's completely normal and wouldn't be noticed by anyone.
* The aliens have mastered the ability to travel across the vast distances of space, manipulate time and matter, but a few planks of wood across the windows should probably keep them out and away from your family. Flawless logic.
* "Quick! The aliens are coming to abduct our son - let's put the children alone in a room, whilst we split up and I wander down the hallway to see why the tv just came on, leaving them totally unprotected." Flawless logic part 2.
* The "expert" says you can't take the implant out, because every time you try, it goes deeper under the skin...... hmmmm.... if only SOMEONE ELSE could take it out for you..... if only there existed a building you could go to that had people with surgical training and medical equipment.... pity no such place exists.
* So both the parents are witness to missing time, strange dreams, random cuts/bleeding, they see the video taps blur and miss time, they are the only house 3 different types of birds crash into, they find their son outside without the alarm going off, they all have memory loss, the kids draw pictures of aliens, the alarm goes off without reason, the kitchen items are arranged to give perfect images of highly advanced geometric shapes, photos vanish without a trace, but when "aliens" are suggested as being behind it the guy flips out and starts laughing - "you can't be serious, there's no such thing as aliens, thats insane, its completely beyond the realm of possibility, there's no life anywhere in the universe except for earth, I'm an architect, I know that for a fact - hell, there's probably a perfectly normal explanation for everything we've both been witness to - it probably happens all the time. Aliens - you're crazy loco".
* In real life, public health department officials always call you back to only utter mysterious and ominous phrases like "its almost as it something strange was drawing them to your house" [insert dramatic sound effect here] just at the exact moment something weird and unexplainable has happened to you.
* The "expert" says the aliens always take the one they first make contact with - which turns out to be the older brother, not the younger brother as the movie makes us believe; and yet THREE MONTHS LATER the mother is shocked to discover the eldest son had been drawing pictures of aliens and she never knew it! [insert another dramatic sound effect here] - er, HELLO!! of course he was the first contact if they took him! DUH!
* Its just as well, three months later, the radio/walkie-talkie has been left switched on in a box of toys, and the batteries still work, and the aliens use the exact same frequency, otherwise the mother wouldn't be able to hear her son talking on it somewhere.
* "Oh yeah, I almost forgot to mention it - your son has geometric brandings all over his body - obviously you're both busy parents and you wouldn't possibly notice it - but no biggie, it's probably perfectly normal".... and lets not refer to it at any point in the movie again.
