You know, after the whole Roswell and X Files debacle I really wasn't all too interested about the "alien" television show. The aforementioned shows were good but they were definitely lacking.
I personally think Kyle XY has found the *it* factor.
Imagine taking a 17 year old kid who is from a different country and is suddenly plunked down in the middle of America with no means of communication. Well then, you've got Kyle. He is about as strange as they come. A human shaped being and no belly button and no information to draw from as to how to interact with other beings.
Now it would be boring to just watch a show about a kid who is seemingly another life form and doesn't know how to communicate, just as it would be boring to watch a foreign exchange student during your lunch period right before chem class. The interesting thing about this show is that the voice overs done by Kyle walks the audience through his emotions and his thoughts as he is remembering his first days as a human.
It is the most beautiful experience; almost as if you looking at the world through a newborn's eyes. You see what they see and you hear what their first thoughts were. Beautiful.
Since ABC doesn't really have a good Friday line up coming in the Fall, I'd like them to keep this show around to see what comes of it. It sucks you in with wondering what Kyle is.
