Two style films are blockbusters both which Netflix/Amazon aren't really after...Animation and Action Films. Action films are things people want to watch in theatres as most home theaters due to house sizes don't have mega screens, IMAX digital projectors, and all the additional things that movie theaters do (motion seats, 3D, etc). Add in the reports of JJ Abrams leaving Paramount, they are losing the biggest action film/sci-fi/blockbuster producer the studio current has. Animation is something Netflix is getting into now but still Paramount/Viacom will have to choose netflix over their personal endeavors. Amazon however is moving the opposite way with more adult focused fare than kid fare.
