Really liked it. At first the first half was boring. But, the 2nd half was good aside from the usual love story. Lots of old Spielberg references, E.T. Goonies, Jurassic Park, Close Encounters, and a bit of Cloverfield alien style. It even had a titanic-ish scene where the amulet of the boy's mom photo in it, gets magnetized on the metal pieces that were flying to reform the spaceship. Yes, it felt like Goonies only instead of treasure pirate hunters, we have high school zombie filmmakers.
And stay for the end credits because of a short film of the main protagonists' school film project called, "THE CASE" they made throughout the movie ala 80's zombie style short film. LOLZ stuff. :P
8/10.
