Cloverfield:
Read the site. Japanese dude trying to make the perfect drink. Scrapes bottom of ocean floor, finds his ingredient, creates Slusho.
Guy from movie celebrating moving to Japan to work for Slusho. Every drinks vast amounts of Slusho in NYC that night.
Suddenly a monster appears... could it be it was from.... the ocean? Hmmm... And it's targetting those who drank Slusho, made from a mysterious ingredient found along the ocean bottom... HMMM!
Judging from shots from the trailer, the damage done to the statue of liberty, etc... I'm thinking of a Cthulu based monster.
