Netflix is mostly uninterested in theatrical distribution so the main practical impact of this most of us see day to day may be less theatrical release movies and probably fewer higher budget films being made at all.
Caveats include that the deal has to actually get regulatory approval in the U.S. and EU and survive potential (inevitable?) shareholder lawsuits. Netflix's offer reportedly involved less cash and more debt. Paramount/Skydance argued regulatory approval and the heavy debt made Netflix's offer less attractive than their own despite Netflix's higher top-line price.
