The family is clueless about what is going on in their house until it becomes a pop culture phenomenon. Colby's family is ready to pull the plug on the operation until they discover Colby is pulling in $17k a week on the site, including a major sponsorship deal. Once the family is aware that they are being watched, the show begins to fall apart, leading the family to do anything to keep the money pouring in.
I-See-You.com isn't that funny a movie. Although some of the dialogue is incredibly witty, there isn't enough of it. To compensate, the movie goes for shock value. There's a sub-plot about Colby and Audrey hooking up before their parents got married, as well as one about Audrey's mom, Lydia (Rosanna Arquette), being a nymphomaniac. Except for producing more sexual situations in the first 5 minutes than most porn movies, the jokes add little to the movie's plot.
Although it fails to be entertaining as a comedy, I-See-You.com is great at pointing out how ridiculous reality TV shows are, and how every one of them eventually becomes a "scripted" show to keep viewers. When the family has no idea they are being broadcast, the show is a hit. Once they are clued in, however, the magic is lost and the producers have to step in and manufacture drama to keep viewers. I-See-You.com is incredibly accurate at showing how Reality TV shows slowly degenerate over time, as well as the effect it takes on the family once they begin acting like caricatures of themselves.
Aside from a few deleted scenes, the only extra is a short featurette called "15 Minutes of Fame". It isn't that interesting and is mostly the director trying to convince the audience that he had the idea long before the Reality TV and YouTube boom.
Unless you think sexual humor is "where it's at" or want to see either Baelyn Neff or Rosanna Arquette in certain situations, it's really hard to recommend I-See-You.com.
