Superb movie but can be better

Rating: 7/10 (27 June 2009)

Although Nicolas Cage is looking old but he is still the man to act in this movie.
Let me get straight to the point. First, the story is interesting. Students draw a picture and put it in a seal envelope, how the school bury the time capsule into a big hole in front of the school gate. Apparently, from the scene the movie changes to horror (the kid scratching the door with her fingernail) and change then change to science fiction (UFO).
I do not know what should i called this movie, horror, drama or science fiction? Overall, the movie still worth for us to go and see. That's all
