This was the first time I saw a movie that had nothing close to a human antagonist, yet it kept me glued to the screen. Sure I've read a few novels of the kind but surely they weren't "oh I'm glued" stuff. Everybody at least once in their life dreams of something like this and this movie makes it believable. After watching the movie I really thought that Ethan & Julie must have dated 'cause their conversations were just flowing. Definitely a must see.
