Why do I have to complete a 'quick survey'?

Because you're on an illegal site, which is designed either to scam you or to infect your computer. Legal sites don't have surveys, although they may have commercials. The only legal sites to watch this show are cwtv.com and maybe hulu.com. Ditto for movies. Any site that claims to have free movies is illegal, especially if they offer movies that are still in theaters, and is probably just a honeypot designed to spread viruses.
