If you're talking about streampix, read the disclaimers [1] and see why Netflix still wins (availability, selection, not tethered to one set-top-box, always on-demand, no random fees/taxes tacked on, doesn't require bundling to a subscription level). Until that changes, Netflix has nothing to worry about.

"Not available in all areas. Set-top box required to access On Demand on TV. Programming not available On Demand in all areas. Basic Service subscription required to receive other levels of service. Not all programming available in all areas. Equipment, installation, taxes and franchise fees extra. Pricing subject to change. Streampix included with the following tiers of service: Blast Plus, HD Preferred Plus XF Triple Play, HD Premier XF Triple Play and HD Complete XF Triple Play. Services and features subject to change..."

Except for the STB interface. At least the mobile app is decent.

It's not like Netflix is fantastic by itself. It's serviceable, but the player is very rudimentary, and often has severe issues with things like subtitles.
