I'll Follow You Down

This came on TV the other day and I had nothing else to do. I didn't know what the movie was about, or who the actors were. I recognized Haley Joel Osment, and kind of did a double take. (More of the "Yikes. Has it been that long?" kind.) The story is a sci-fantasy story, but that's not the driving factor. There is little (almost none) in the way of special effects, and it doesn't need it. The plot centers around Erol, whose father left for a conference, and disappeared. But there is more to it than just a disappearance, and with his grandfather he figures it all out. I thought the acting could have been better in places, as it was very character driven. I won't put spoilers, but I didn't see the ending coming. Definitely worth getting the popcorn out for.
