Imagination is fine. Breaking the laws of the universe makes for bad entertainment.
The data that this guy is looking for doesn't exist. It's possible could see a bomb sitting at his feet and just glanced over it. But it's impossible that he opens a door he never opened and finds something he never saw.
Independence Day VS Battle Los Angeles
In IE the aliens come for our natural resources. They never say what exactly but we could theorize that it's a rare element that they can't find elsewhere. Then they proceed to obliterate us with giant weapons from high up in the sky, also believable.
In Battle Los Angeles they come for our water (what?????) They give a shitty excuse that our water is liquid. But come on, they don't have fucking microwaves?
1. Find comet
2. Melt comet
Then... They launch a GROUND ASSAULT? Really? These guys likely invented faster than lightspeed technology to search the universe for planets with melted ice just so they could drop shock troops onto the ground and get raped by people with seriously low tech weapons.
Independence Day while not supremely realistic is definitely more realistic than Battle LA, which makes it a better movie.
Likely if aliens do show up they'll simply vaporize us for orbit and take what they want after the planet is void of any disturbances. Not much of a movie but definitely realistic.
What would make a better movie:
The earth falling out of orbit because a giant asteroid crashed into the moon fucking shit up.
or
The earth falling out of orbit because space rabbits landed on earth and they're really fat?
TLDR: Stop defending lazy writing.
