A gorgeous landing page with search & metadata skinned over a decade of media licensing deals, proprietary critic networks, and a monetized ad ecosystem—impossible to clone without Fandango's IP & relationships.

You can rebuild the site in a weekend, but not the 25-year critic network, Fandango's box-office licensing, proprietary aggregated ratings, or the media industry relationships that are Rotten Tomatoes' actual moat.

A prompt can rebuild

A polished entertainment hub with user accounts, search, browse, and movie/TV metadata display. A prompt can rebuild the UI layouts, forms, and basic page structure in a day or two.

What you can't see

Multi-year backend: managed auth (Auth0/Clerk), production Algolia search infrastructure, JWPlayer video streaming, Fandango ticket integration, proprietary critic/user ratings DB, watchlist persistence, device tracking, ad-serving platform (MPS/Viant), analytics stack (Adobe, Chartbeat), and real-time content feeds.
