Very, very good. It’s incredibly focused – a simple setup, believably basic character motivations and very little exposition. This annoyed the crap out of me while I was watching it, because why doesn’t everyone write like that? Rule number one: only include what you need to include.
You can tell that the effort of avoiding the genre cliches got to the makers, because as soon as the end credits start rolling (which is the one and only time the film breaks character) the most epic, giant monster-est piece of music ever composed kicks in. It’s called “ROAR! (Cloverfield Overture)” and it lasts twelve minutes. It’s almost unbearably awesome.
Have you ever truly tested your awesome containment quotient(ACQ)? If you do often rieach your limits you should install Ass Kickin’ Dampeners. Or you could cheap out and get some Modular Dullness Buffers.
Also Rieaching your limits is more dangerous than just plain Reaching.
