To clear up the ending: It was NOT meant to be a "YAY! we win!" movie. It wasn't about humanity fighting this monster it was about an archive of these friends who went through that night through there perspective, death and all, this wasn't meant to be a happy film it was meant to be bleak with a bleak hopeless ending.
I don't. I think it's not a film about "Oh lol everyone died!", but it's just the director's representation of..... well, an archive of stuff from the "cloverfield incident".
Which of course, makes more questions and more answers. Why would the US government keep a piece of film about something they already know lots about? They obviously know lots about the Monster, as we found out about the movie, with the alien / monster carcasses being wheeled through the makeshift base...
They obviously know about the monster.
and it obviously wasn't a coverup, since the news stations all had footage of the monster and other people knew about it. (The guy's mother ringing to see if he's ok)
So why would they keep something so worthless as a tape of the monster in a... I dunno, "top secret cloverfield archive"? (remember at the beginning, with the whole "for your eyes only, property of the U.S government, etc..)
Simple. For that thing hitting the ocean at the end. They wouldn't know where it came from, would they? It wasn't on fire when it came down, was it? So it obviously didn't enter the atmosphere. (then again, maybe it's totally heat-proof, since it was never of fire, even after all those explosions and shit)
See? It's a good movie, since we're all still talking about it!!!
